	Commit message (Collapse)	Author	Age	Files	Lines
*	utils/grid.py: Use own-implemented JIT-optimized "rotate_center()"	Aaron LI	2016-10-26	1	-3/+3
\| \| \| \|	Also remove the dependence on "scipy".
*	grid.py: Override "make_coordinate_grid()" using JIT-optimized version	Aaron LI	2016-10-25	1	-46/+2
\| \| \| \| \|	Remove the original "make_coordinate_grid()" function, and rename the "make_coordinate_grid_fast()" to override the former one.
*	grid.py: Change "make_coordinate_grid_fast()" parameters	Aaron LI	2016-10-25	1	-11/+16
\| \| \| \| \|	Change the parameters of "make_coordinate_grid_fast()", make it share the same parameter list as "make_coordinate_grid()".
*	grid.py: Optimize "map_grid_to_healpix()" using "numba.jit"	Aaron LI	2016-10-25	1	-11/+19
\| \| \| \| \|	There are some limitations with the numba JIT, which are commented in the code.
*	utils/grid.py: Add optimized "make_coordinate_grid_fast()"	Aaron LI	2016-10-25	1	-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()"
*	galactic/snr.py: Implemented missing but necessary functionalities	Aaron LI	2016-10-17	1	-1/+1
\| \| \| \| \| \| \| \|	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 LI	2016-10-17	1	-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 SNRs	Aaron LI	2016-10-17	1	-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.
