\| \| \| \| \| \|	Generate requested number of random points within the sky. Signed-off-by: Aaron LI <aly@aaronly.me>
*	sky.py: frequency has implicit unit "MHz"	Aaron LI	2017-07-19	1	-11/+22
\| \| \| \| \| \|	And some minor updates Signed-off-by: Aaron LI <aly@aaronly.me>
*	sky.py: Default to assume a flat sky for patch	Aaron LI	2017-07-19	1	-5/+10
\| \| \| \| \| \|	Use "CAR" (Cartesian) projection instead of "TAN" (tangential) projection. Signed-off-by: Aaron LI <aly@aaronly.me>
*	Use [arcsec] as the unit for pixel size and resolution	Aaron LI	2017-07-19	1	-13/+14
\| \| \| \|	Signed-off-by: Aaron LI <aly@aaronly.me>
*	sky.py: Write PIXELSIZE, RA0, and DEC0 to header for patch sky	Aaron LI	2017-06-19	1	-0/+3

*	sky.py: Fix FITS header write	Aaron LI	2017-05-27	1	-4/+8
\|
*	sky.py: Add "area()" method	Aaron LI	2017-05-25	1	-0/+21
\| \| \| \| \| \|	XXX/FIXME --------- Consider the spherical coordination and WCS sky projection!!
*	sky.py: Implement method "reproject_to()"	Aaron LI	2017-05-22	1	-8/+102
\| \| \| \| \| \| \| \| \| \|	This method reproject the given sky/image onto the grid of its own, using the ``reproject`` package [1]. However, the performance may be a problem and needs optimization or rewrite. [1] reproject: https://github.com/astrofrog/reproject
*	sky/SkyPatch: Add wcs and region coverage check	Aaron LI	2017-05-22	1	-0/+56
\| \| \| \|	NOTE: only TAN sky projection supported.
*	sky.py: Flatten 2D image of sky patch to 1D for easier processing	Aaron LI	2017-05-21	1	-14/+21
\| \| \| \| \|	Flatten the image array to 1D makes it similar to the HEALPix map array, therefore, it is easier to deal with both cases.
*	Add sky.py to support both sky patch and HEALPix all-sky map	Aaron LI	2017-05-21	1	-0/+272
