* utils/cosmology.py: Add methods Dc() and Dc_to_redshift()Aaron LI2017-10-021-0/+48
| | | | | | * Dc(): simple wrapper on astropy cosmology's comoving_distance() * Dc_to_redshift(): determine the redshift w.r.t. the input comoving distances using interpolation.
* utils/units.py: Add eV and keV to temperature conversionsAaron LI2017-09-261-0/+3
|
* utils/io.py: Add function "csv_to_dataframe()" to support CSV commentsAaron LI2017-09-031-2/+35
|
* utils/convert.py: Remove the slow, astropy.units based functionsAaron LI2017-09-011-64/+24
|
* utils/draw.py: Replace "ellipse()" with the `skiimage' versionAaron LI2017-08-311-27/+96
| | | | | | | Also do not use Numba JIT here. Credit: scikit-image - skimage/draw/draw.py https://github.com/scikit-image/scikit-image/blob/master/skimage/draw/draw.py

* Fix the warning on scipy.ndimage.zoom output shape calculationAaron LI2017-08-141-1/+4
| | | | | | | | | scipy.ndimage.zoom calculate the output/zoomed image shape with round(), while the old versions use int() instead. When the two calculations are different, a warning is raised. This commit fixes the calculation mismatch. Signed-off-by: Aaron LI <aly@aaronly.me>
