Detailed Description

Make Look-Up Table for FGCM.

This task computes a look-up-table for the range in expected atmosphere
variation and variation in instrumental throughput (as tracked by the
transmission_filter products).  By pre-computing linearized integrals,
the FGCM fit is orders of magnitude faster for stars with a broad range
of colors and observing bands, yielding precision at the 1-2 mmag level.

Computing a LUT requires running MODTRAN or with a pre-generated
atmosphere table packaged with fgcm.
