HDU0

EXTNAME = FLUXCALIB

Flux calibration array ‘fluxcal’, such that calibrated flux = uncalibrated flux / fluxcal. 2D array of dimension [nspec, nwave]. nspec is the number of fibers per camera. nwave in the length of the wavelength array. The flux calibration of all fibers share the same wavelength grid (given in HDU WAVELENGTH). The units are electrons / (10^{-17} ergs/s/cm2), such that the calibrated flux has units of 10^{-17} ergs/s/cm2/Angstrom. The flux calibration is obtained by comparing the sky subtracted and flat-fielded flux from standard stars in the sframe file with stellar models from the stdstars file. This calibration of the total flux is valid for point sources only. For extended sources, one may consider using a ‘fiber flux’, which is the flux one would collect in a 1.5 arcsec diameter aperture centered on the object when observed with a 1 arcsec FWHM Gaussian seeing. The ‘fiber flux’ can be obtained by multiplying the calibrated flux array of each fiber by the corresponding entry in the FIBERCORR table column ‘PSF_TO_FIBER_FLUX’.

EXTNAME = WAVELENGTH

Wavelengths at which the flux calibration is evaluated, in Angstrom. Note the wavelength is in the solar system barycenter frame, so that the calibration can be directly applied to the science frame fluxes which are on the same wavelength grid. In order to compare the calibration from different exposures, one has to convert back the wavelength array to the observer frame, by dividing it by Doppler factor saved in header keyword HELIOCOR in HDU0. See also the frame WAVELENGTH documentation for more details.

EXTNAME = FIBERCORR

Table with the following adimentional scaling factors for each fiber:

FLAT_TO_PSF_FLUX = normalized ratio of the flat-fielded flux to the total flux for point sources; already included in the flux calibration array.

PSF_TO_FIBER_FLUX = ratio of total flux to ‘fiber flux’; not included in the flux calibration array.

A ‘fiber flux’ is the flux one would collect in a 1.5 arcsec diameter aperture centered on the object when observed with a 1 arcsec FWHM Gaussian seeing. The variation of plate scale in the focal plane, the seeing condition of the observations, the fiber positioning errors, and the intrinsic angular size of the sources have been considered to compute those scaling factors.

Optional

Notes and Examples

We may add an additional HDU with EXTNAME=METADATA containing a binary table with one row per standard star giving the details of which model was used, etc. This is not yet implemented and details TBD.

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.

For targets with a non-zero proper motion, FIBER_RA and FIBER_DEC refer to the position at the reference epoch (but note that the proper-motion correction has been applied at the time of the observation, it is just not recorded in FIBER_RA and FIBER_DEC).
