Summary: | Frame files contain the raw extracted electrons from DESI data, without any further calibration. |
---|---|
Naming Convention: | frame-{CAMERA}-{EXPID}.fits , where {CAMERA} is
one of the spectrograph cameras (e.g. z1 ) and {EXPID}
is the 8-digit exposure ID. |
Regex: | frame-[brz][0-9]-[0-9]{8}\.fits |
File Type: | FITS, 70 MB |
Number | EXTNAME | Type | Contents |
---|---|---|---|
HDU0 | FLUX | IMAGE | Extracted flux in electrons per Angstrom |
HDU1 | IVAR | IMAGE | Inverse variance of the extracted flux |
HDU2 | MASK | IMAGE | Bad value mask; 0=good |
HDU3 | WAVELENGTH | IMAGE | Wavelength grid of the extraction (Angstrom) |

EXTNAME = FLUX
2D array of extracted flux[nspec, nwave] in units of electrons per Angstrom. nspec is the number of fibers per camera. nwave in the length of the wavelength array. The spectra of all fibers share the same wavelength grid (given in HDU WAVELENGTH).

EXTNAME = WAVELENGTH
1D array of wavelengths in Angstrom, in vacuum (not in air). For science exposures (in opposition to calibration exposures), the wavelength in is the rest frame of the solar system barycenter. The Doppler factor applied to the observed wavelength at the telescope to convert them to the barycentric frame is saved in header keyword HELIOCOR in HDU0. In other words, WAVELENGTH = BARYCENTRIC_FRAME_WAVELENGTH = HELICOR * OBSERVER_FRAME_WAVELENGTH. Note a single factor has been applied to all fibers despite a small difference in pointing.

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 </DESI_TARGET/fiberassign/tiles/TILES_VERSION/TILEXX/fiberassign-TILEID>` design step; thus the following columns can have different values than in the :doc:`desitarget products </DESI_TARGET/TARG_DIR/DR/VERSION/targets/PHASE/RESOLVE/OBSCON/PHASEtargets-OBSCON-RESOLVE-hp-HP>`: 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
).
