Description

Write software to analyze lossy fiber CCD images. Preliminary work started at DESI June 2017 collaboration meeting. Need to solve simultaneously for average lamp spectrum, fiber transmission.
Difficulties
- there is an apparent chromatic variation of transmission (but slow/smooth variation with wavelength)
- the fiber/wavelength coordinate mapping on CCD image needs to be accurate and it's different from fiber slit.
- more defocusing of the lossy fiber would help

Research direction

The issue names no files, tests, or entry points. Start by locating existing lossy-fiber, CCD-image, or spectral-analysis work in the repository and review the preliminary work from the June 2017 collaboration meeting; the desired analysis scope and completion criteria still need to be established.
