[ ] twinkle observation history magnitude system
- https://github.com/LSSTDESC/Twinkles/blob/master/python/desc/twinkles/twinkles_sky.py : exposure time is 30s
- This sky use AB magnitude. So I can either convert all the fluxes into AB magnitude flux or convert the sky into ngmy : http://www.sdss.org/dr12/algorithms/fluxcal/#SDSStoAB
[ ] om10 exposure time
[ ] size doesn't match at all
[ ] cornerplot is meaningless - the quasars might not be observable..
