The spectra of all fibers share the same wavelength grid (given in HDU WAVELENGTH). cframe.flux = ( frame.flux / flatfield - sky ) / fluxcalib. This calibration of the total flux is valid for point sources only. For extended sources, one may consider the '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 flux array of each fiber by the corresponding entry in fibermap table column 'PSF_TO_FIBER_SPECFLUX'. This is the quantity to use for comparison with the photometric FIBERFLUX values given for several band passes in the fibermap.

These measure the signal-to-noise squared weighted by which wavelengths matter most for different target types, e.g. QSOs weight blue wavelengths more while ELGs weight redder wavelengths more due to the wavelengths of the observed emission lines. For more details, see section 4.14 of `Guy et al 2023 `_. 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 :doc:`fiberassign ` design step; thus the following columns can have different values than in the :doc:`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``).
