stdstars-SPECTROGRAPH-EXPID.fits

Summary:

This file contains the normalized standard star models fitted to the frame data.

Naming Convention:

stdstars-{SPECTROGRAPH}-{EXPID}.fits where {SPECTROGRAPH} is the single-digit spectrograph number 0-9, and {EXPID} is the zero-padded 8-digit exposure number.

Regex:

stdstars-[0-9]-[0-9]{8}\.fits

FITS Header Units

HDU0

EXTNAME = FLUX

2D array of best fit standard star model fluxes, in units of 10^{-17} ergs/s/cm2/A, at high resolution, including the Milky Way extinction, and the Doppler shift from the fitted radial velocity. The size of the array is [nspec, nwave]. nspec is the number of standard stars and nwave in the length of the wavelength array.

Notes and Examples

For the SURVEY=cmx m33 tile (TILEID=80615) tile and all the SURVEY=sv1 tiles (except TILEID=80971-80976, the dc3r2 ones), proper-motion correction was applied at the fiberassign design step; thus the following columns can have different values than in the desitarget products: TARGET_RA, TARGET_DEC, REF_EPOCH, PLATE_RA, PLATE_DEC, and PLATE_REF_EPOCH.
