Develop a program for fitting lyot drift #10
Description
Using the #7 scans, identify observing programs that can profile absorption lines so we can track filter drift/rest wavelength over time.
Use this paired-down scan of just 5-7 pts on the line to track it.
In this notebook about 1/2 down there are a series of daily plots that used our wide flat scans to track the 1074.9nm absorption line and compare that to a spectrum convolved with the solar atlas. These show a noisy trend of the measured spectrum drifting until we apply a wave offset change January 17th. It also looks like there is a bug/offset in this analysis because data and model seem to have the best agreement the day before the offset was changed from 1.87 to 1.94. But we definitely see the shift over time.
