* foregrounds.py: Add new component extragalactic/clustersAaron LI2016-10-221-3/+5
|
* Support new simulation component: extragalactic/clustersAaron LI2016-10-223-0/+695
| | | | | | | | | | | Support simulate the radio emission from clusters of galaxies. Currently only the radio halos is considered, while the radio relics need more investigations. Also, this simulation requires a cluster catalog derived from the Hubble Volume Project simulation. NOTE: not tested at the moment
* Add utils/random.py: Custom random utilitiesAaron LI2016-10-221-0/+51
| | | | | Currently implement "spherical_uniform()" to generate random points uniformly distributed on the spherical surface.
* galactic/snr.py: Fix wrong astropy quantity operationAaron LI2016-10-221-1/+1
| | | | | | | When two quantities of same unit class divides, to get the correct numerical value, whether use `.decompose().value`, or just convert to plain Python object, e.g., `float(...)`, which will fail if the input quantity is not dimensionless.
* galactic/snr.py: Add one reference and update docstringAaron LI2016-10-221-5/+12
|

| | | | All HEALPix maps used are in *RING* ordering.
* galactic/{freefree,synchrotron}.py: Fix small bugsAaron LI2016-10-182-2/+2
| | | | | * freefree.py: Add the missing "/" to the config "halphamap" * synchrotron.py: Fix "comp" to have the correct value
* foregrounds.py: Fix two small bugs and test is OKAaron LI2016-10-181-4/+5
| | | | | | * Fix the wrong import path * Add the missing "output_dir" property * Tweak the comments/messages a bit
* Add "foregrounds.py" as the interface to foregrounds simulationAaron LI2016-10-182-3/+205
| | | | | This module provides a simple/easy-to-use interface to the simulation of various supported foreground components.
* galactic/synchrotron.py: Add preocess(), postprocess, _make_filepath()Aaron LI2016-10-181-41/+75
| | | | | | * Add the "preprocess()" and "postprocess()" for a better interface; * Add "_make_filepath()" to compose the output filename; * Reorder some methods for consistency.
* galactic/freefree.py: Add preocess(), postprocess, _make_filepath()Aaron LI2016-10-181-52/+90
| | | | | | | * Add the "preprocess()" and "postprocess()" for a better interface; * Add "_make_filepath()" to compose the output filename; * Reorder some methods for consistency; * Some refactorings and cleanups.
* galctic/snr.py: Add "preprocess()" and "postprocess()" methodsAaron LI2016-10-181-70/+86
| | | | | | | * Add "preprocess()" and "postprocess()" methods * Add the "name" property * Tweak the places of preparation procedures been invoked * Reorder some methods
* galactic/snr.py: Fix the existence check of dir of catalog ouputAaron LI2016-10-171-1/+1
|
* galactic: Move the "simulate()" method; Add "UNIT" keywordAaron LI2016-10-172-26/+28
|
* galactic/snr.py: Create dir if necessary and adhere clobber configAaron LI2016-10-171-0/+11
|
* galactic/snr.py: Fix various issues, and works almost OK.Aaron LI2016-10-171-7/+22
| | | | Barely test and seems OK.
* configs/manager.py: Fix the bug that breaks specifications loadingAaron LI2016-10-171-1/+4
| | | | | | | The "filter()" returns an iterator, that is consumed after the use, therefore, the "specfiles" is used by the print under "DEBUG_FG21SIM". Then "specfiles" is empty and thus prevents the reading of the specification files.
* configs/validate.py: Add "check_galactic_snr()" for "galactic/snr"Aaron LI2016-10-171-0/+16
|
* bin/fg21sim: Support new component "galactic/snr"Aaron LI2016-10-171-1/+5
| | | | Also update the general config for the new "galactic/snr" component.
* galactic/snr.py: Implemented missing but necessary functionalitiesAaron LI2016-10-172-26/+165
| | | | | | | | The necessary but missing functionalities to simulate the Galactic SNRs emission maps are implemented, and this new emission component is ready for testing. Also fix a typo in "utils/grid.py".
* utils/grid.py: Implement "map_grid_to_healpix()"Aaron LI2016-10-171-9/+29
| | | | | | | | The "map_grid_to_healpix()" maps the generated coordinate grid to a HEALPix map. Note that only effective HEALPix pixels are returned instead of a full HEALPix map. TODO: Try to avoid the explicit for loop to optimize the speed.
* Add utils/grid.py: Make coordinate grids for SNRsAaron LI2016-10-171-0/+157
| | | | | | | * make_coordinate_grid(): Make a Cartesian coordinate grid according to the specified center coordinate, size and grid resolution. * make_grid_ellipse(): Also generate an (rotated) ellipse and place into the coordinate grid.
* galactic: Add new component "galactic/snr": supernova remnantsAaron LI2016-10-172-0/+256
| | | | NOTE: very preliminary, and missing many necessary functions!
* configs: Add new section "[galactic][snr]" for SNRs simulationAaron LI2016-10-171-1/+19
| | | | NOTE: very preliminary and may change at any time!

|
* configs/manager.py: Change __init__() to load user configAaron LI2016-10-171-9/+15
| | | | | | | | Change the "__init__()" method to load the user configurations (i.e., by invoke the "read_userconfig()" method) instead of loading extra general configurations. Method "getn()": also check the validity for the parameter "sep".
* configs/manager.py: Various updates to docstring and comments.Aaron LI2016-10-171-23/+44
| | | | No functional changes.
* utils/draw.py: List the functions taken from "scikit-image"Aaron LI2016-10-171-2/+8

|
* configs: Update get_path() to take care None and non-string valueAaron LI2016-10-151-3/+24
| | | | | | * Return None if specified config is None or not exist * Raise ValueError if specified config is non-string * Update comments
* Add utils/convert.py: Implement brightness temperature conversionAaron LI2016-10-151-0/+63
|
* Add utils/draw.py: draw circles and ellipsesAaron LI2016-10-151-0/+128
| | | | | | | | | These functions will be used to draw the image of a SNR or a radio halo. These functions are copied from the `scikit-image` project. Thanks! scikit-image: http://scikit-image.org/docs/dev/api/skimage.draw.html
* configs: Switch to use `pkg_resources` to access config specsAaron LI2016-10-151-10/+19
| | | | | | | | | After this switch to `pkg_resources`, this package can also be installed as an EGG (a zip archive), which is more generic.

* Add data/snr.py to retrieve Green's Galactic SNRs catalog dataAaron LI2016-10-152-0/+334
| | | | | | Thanks D. A. Green for the Galactic SNRs catalog (294 objects)! http://www.mrao.cam.ac.uk/surveys/snrs/
* Fix an import; Update one pattern and a commentAaron LI2016-10-141-2/+2
|
* configs: Support env variable "DEBUG_FG21SIM" for debuggingAaron LI2016-10-141-0/+3
| | | | | | Since the logging is not avaiable at the moment, we can only use the plain `print` for debugging, if the environment variable "DEBUG_FG21SIM" is defined.
* configs/validate.py: Check component configs only if enabledAaron LI2016-10-121-22/+26
|
* configs/validate.py: Add checker for [galactic][freefree] configsAaron LI2016-10-121-0/+18
|
* Tweak the docstring stylesAaron LI2016-10-112-6/+12
|
* galactic/freefree: Mask regions where absorption is uncertainAaron LI2016-10-111-4/+25
| | | | | | | | | | | | | | * Mask the regions where the dust absorption is too high to well determine the true Halpha absorption. There are regions (e.g., Galactic plane) have too large dust absorption which cause float overflow when applying absorption correction to the Halpha map. * Fix a bug on the wrong parameter passed to "_calc_ratio_a()" method in "_simulate_frequency()" * Move "_correct_dust_absorption()" invokation from "simulate()" to "_simulate_frequency()" Already tested and OK!
* utils: healpix2hpx & hpx2healpix: Remove "header" parameterAaron LI2016-10-111-35/+20
| | | | | | | | * healpix2hpx(), hpx2healpix(): Remove the "header" parameter, thus the "data" parameter can only be either the filename or a HDU; * healpix2hpx(): Remove the check on "ORDERING", since "read_fits_healpix()" always return the HEALPix data in RING ordering; * Small updates to the log messages and comments.
* utils: Update documentations, also fix stylesAaron LI2016-10-112-35/+53
|
* Update bin/fg21sim to support Galactic free-free componentAaron LI2016-10-111-0/+4
| | | | | | | | | * bin/fg21sim: check the "common/components" config to simulate the enabled components; * bin/fg21sim: add Galactic free-free component support; * galactic/freefree.py: fix missing attributes. NOTE: simulated free-free maps are WRONG!! Need check/debug!
* galactic: Add free-free component simulationAaron LI2016-10-113-0/+247
| | | | | | | * New class "galactic.FreeFree" to simulate free-free emission * Add new config section "galactic/freefree" NOTE: current untested
* galactic/synchrotron: Merge up/downgrade Nside to load methodAaron LI2016-10-111-45/+29
| | | | | | | * Merge the upgrade/downgrade resolution w.r.t Nside to the map loading methods; * Update the variable names; * Check the status of smallscales addition.
