Instrument configuration files

filename	description
${INSTRUMENT}.par	miscellaneous instrument-specific parameters measured at the telescope
desi-${DOCDB_NUMBER}.dat	patrol disk / fiducial positions on focal surface z1 from docdb
fiberpos-${INSTRUMENT}.dat	table of petal, hole, posid, serial, canbus, canid, type, X, and Y
fiducial-${INSTRUMENT}.dat	coordinates of fiducials in q, s system defined in DESI docdb-742
positioner-${INSTRUMENT}.dat	coordinates of positioners in q, s system defined in DESI docdb-742
PRISM.par	coefficients for PRISM tuning vs. zenith angle applied as polynomials to zenith distance
SURFACE.par	coefficients to transform from cylindrical radius to q coordinate defined in DESI docdb-742
GFA.par	paremeters from ray trace describing geometric layout of GFA

In addition, the following files from Steve Kent’s raytrace program provide coefficients for tuning distortion parameters as a function of zenith angle:

• rotcoeff.par
• scalecoeff.par
• xfcoeff.par
• xgcoeff.par
• xgobscoeff.par
• xoffcoeff.par
• xzcoeff.par
