All HEALPix maps used are in *RING* ordering.
|

* freefree.py: Add the missing "/" to the config "halphamap"
* synchrotron.py: Fix "comp" to have the correct value
|
|
|
|
|
|
| |
* Fix the wrong import path
* Add the missing "output_dir" property
* Tweak the comments/messages a bit

This greatly simplifies the "bin/fg21sim" script, and also makes the
script more generic.

This module provides a simple/easy-to-use interface to the simulation of
various supported foreground components.

* Add the "preprocess()" and "postprocess()" for a better interface;
* Add "_make_filepath()" to compose the output filename;
* Reorder some methods for consistency.

Barely test and seems OK.

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.
|
| |
|
|

|

Also update the general config for the new "galactic/snr" component.
|
|
|
|
|
|
|
|
| |
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".
|
|
|
|
|
|
|
|

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.

* 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.

NOTE: very preliminary, and missing many necessary functions!

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".
|
|
|
|
| |
No functional changes.

* Return None if specified config is None or not exist
* Raise ValueError if specified config is non-string
* Update comments

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!

After this switch to `pkg_resources`, this package can also be installed
as an EGG (a zip archive), which is more generic.

Add two new requirements: beautifulsoup4, requests
|
|
|
|

This script invokes the data/snr.py .

Thanks D. A. Green for the Galactic SNRs catalog (294 objects)!

The default config specifications are required and should be installed.
TODO:
* Figure out the problem why "LICENSE" cannot be installed as well ??

The utils/zea2healpix requires scipy.
|
|
|
|
|
|

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.

Do not quote Make variables, since Make does NOT understand or parse
single- or double-quote characters in any way.

* 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!

* 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.
