DECam utilities The biggest piece right now is a simplified version of A. Patej's nightlystrategy.py, which makes observing plans for nights at DECam. Requires pyephem to run, and can be invoked via: python nightstrat.py 2016-03-13 decaps-tiles.fits gr plan The above makes a plan for the night of 2016-03-13 using the tile centers in decaps-tiles.fits, for the gr filters, and outputs the results to plan.json and sanity plots to plan.png.
