* Revert "utils/convert.py: Use 'utils.units' module"Aaron LI2017-06-241-7/+6
| | | | | | This reverts commit eb660ae70db40d36418f1e4eb886fd9bb02af1a7. Numba cannot recognize AUC/AC classes, or needs further updates
* cosmology: Use default parameters from configurationsAaron LI2017-06-231-1/+5
| | | | Also add configuration option "cosmology/Omegab0".
* utils/convert.py: Use 'utils.units' moduleAaron LI2017-06-231-6/+7
|

|
* utils/cosmology: Add methods DL() and DA()Aaron LI2017-06-191-0/+14
|
* clusters: Move units.py and cosmology.py to utilsAaron LI2017-06-012-0/+287
|
* Add utils/wcs.py with function "make_wcs()"Aaron LI2017-05-221-0/+54
|
* utils/grid: Add function "make_ellipse()"Aaron LI2017-05-221-7/+47
|

| | | | | * Fix the bug that "ellipse()" generate unexpected results. * Update the parameters of "ellipse()" also
* utils/draw.py: Fix a wrong brace in "_ellipse_in_shape()"Aaron LI2016-12-131-1/+1
| | | | | This bug causes wrong ellipse generation, which is the main reason to the strange and wrong SNRs shapes.
* utils: Add download.py with function "download_file()"Aaron LI2016-11-261-0/+112
|
* utils: Rename function "md5()" to "calc_md5()"Aaron LI2016-11-261-1/+1
|
* utils: Add "hashutil.py" with function "md5()"Aaron LI2016-11-211-0/+40
| | | | | | md5(): Calculate the MD5 checksum of the file. Credit: https://stackoverflow.com/a/3431838/4856091
* utils/draw.py: Remove the "Modified BSD" license; Update creditAaron LI2016-11-181-40/+4
|
* utils/healpix.py: Fix the import issueAaron LI2016-11-091-1/+1
|
* utils/__init__.py: Only import "setup_logging" from "logging.py"Aaron LI2016-10-291-3/+0
| | | | | | | | | | Since some modules (e.g., healpix.py) under "utils" involves Numba JIT optimization, which significantly slows the start-up speed, even some consumers (e.g., bin/fg21sim-webui) do not need them at all. Fix various import statements of other modules. NOTE: not test at the moment!
* utils/random.py: Add a note on conversion to (longitude, latitude)Aaron LI2016-10-281-0/+5
|
* utils/rotate.py: Add a new ref. which may help further vectorizationAaron LI2016-10-281-0/+2
| | | | Investigate whether the vectorization will improve the speed.
* utils/fits.py: Add parameter "checksum" for write_fits_healpix()Aaron LI2016-10-271-8/+13
| | | | Also update the docstring and one comment.
* utils/rotate.py: Fix two bugs which cause wrong resultsAaron LI2016-10-261-4/+13
| | | | | | | * Fix the wrong output shape: wrongly swap the row and column * Fix the area mapping method, which may give zero values when the index of the input is integer, which cause problem to calculate the overlapping areas.
* utils/grid.py: JIT optimize "make_grid_ellipse()"Aaron LI2016-10-261-10/+15
| | | | NOTE that the original optional paramter "rotation" is now required.
* utils/grid.py: Use own-implemented JIT-optimized "rotate_center()"Aaron LI2016-10-261-3/+3
| | | | Also remove the dependence on "scipy".
* Add utils/rotate.py: Implement basic image rotationAaron LI2016-10-261-0/+131
| | | | | | | | | The "rotate_center()" function rotates a gray-scale image by a given angle about its center, using the area mapping method or simple nearest neighbor. This function is `numba` JIT-optimized, and can replace the `scipy.ndimage.rotate()` function.
* draw.py: Remove the unused "circle()" functionAaron LI2016-10-251-42/+0
|
* draw.py: Optimize "ellipse()" using numba JITAaron LI2016-10-251-17/+27
| | | | | | | | | | NOTE: However, there are two significant problems: * Cannot figure out why ``nb.optional(nb.types.UniTuple(nb.int64, 2))`` does NOT work. Therefore, make ``shape`` as mandatory parameter instead of optional. * Cannot figure out multi-dispatch that allows both int and float types for ``r``, ``c``, ``r_radius`` and ``c_radius``. Thus only support the int type for the moment.
* draw.py: Optimize "_ellipse_in_shape()" using JITAaron LI2016-10-251-3/+20
