* grid.py: Optimize "map_grid_to_healpix()" using "numba.jit"Aaron LI2016-10-251-11/+19
| | | | | There are some limitations with the numba JIT, which are commented in the code.
* healpix.py: Change all "indices" to "indexes"Aaron LI2016-10-252-19/+19
| | | | Also fix a wrong notation in "random.py"
* healpix.py: Implement "ang2pix_ring" and "pix2ang_ring" with JITAaron LI2016-10-251-0/+213
| | | | | | | | | | To optimize "map_grid_to_healpix()" in `grid.py` which uses "healpy.ang2pix()" using `numba.jit`, implement the latter's functionality explicitly with `numba.jit` support. The implementation simply mimic the corresponding functions "ang2pix_ring_z_phi()" and "pix2ang_ring_z_phi()" in HEALPix's "src/C/subs/chealpix.c". Thanks!
* healpix.py: Optimize "_calc_hpx_indicies()" and "_calc_hpx_row_idx()"_Aaron LI2016-10-251-60/+68
| | | | | Also place "_calc_hpx_row_idx()" before "_calc_hpx_indicies()", which is required by `numba`.
* extragalactic/clusters.py: Speed up "calc_Tb()" significantlyAaron LI2016-10-251-10/+16
| | | | | | | | | Avoid using "astropy.units" in "calc_Tb()", which significantly speeds up this method. NOTE: whether the distance given by the simulation needs additional conversion to derive the *luminosity distance* ??
* utils/grid.py: Add optimized "make_coordinate_grid_fast()"Aaron LI2016-10-251-4/+56
| | | | | | | | Optimize "make_coordinate_grid()" using "numba.jit", which improves the speed a bit, since the other two functions (i.e., "make_grid_ellipse()", and "map_grid_to_healpix()") are much slow and time-consuming. TODO: optimize "make_grid_ellipse()" and "map_grid_to_healpix()"
* extragalactic/clusters.py: Use "Fnu_to_Tb_fast()"Aaron LI2016-10-241-13/+15
|
* convert.py: Optimize "Fnu_to_Tb()" and "Sb_to_Tb()"Aaron LI2016-10-241-0/+65
| | | | | | | | | * Optimize the "Fnu_to_Tb()" and "Sb_to_Tb()" functions by explicitly calculating the conversions, avoiding the slow `astropy.unit` conversions (which is rather slow). The new fast functions are named as "Fnu_to_Tb_fast()" and "Sb_to_Tb_fast()". * Optimize the new functions using `numba.jit` further. * Add `numba` to the dependencies.
* extragalactic/clusters.py: Fix multiple bugs (Test OK)Aaron LI2016-10-221-10/+45
| | | | | | * Fix several bugs, e.g., typo, wrong quantity operation, etc. * Add new method "_calc_specindex()", also allow further improvement * Improve docstrings, comments, and log messages.
* 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

| | | | | * 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

* 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

* 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.

|
* 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

| | | | | | * 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.
