========================= preproc-CAMERA-EXPID.fits ========================= :Summary: Pre-processed spectrograph CCD raw data. :Naming Convention: ``preproc-{camera}-{expid}.fits``, where ``{camera}`` is the spectrograph camera (e.g. "b0", "r1", "z9"), and ``{expid}`` is the zero-padded 8-digit exposure ID. :Regex: ``preproc-[brz][0-9]-[0-9]{8}\.fits`` :File Type: FITS, 194 MB Contents ======== ====== ========= ======== =================== Number EXTNAME Type Contents ====== ========= ======== =================== HDU0_ IMAGE IMAGE Flat-fielded pixel values in electrons [FLOAT] HDU1_ IVAR IMAGE Inverse variance (1/sigma^2) of pixel values [FLOAT] HDU2_ MASK IMAGE Bitmask to flag bad pixels or cosmics [INT] HDU3_ READNOISE IMAGE Flat-fielded readout noise in electrons [FLOAT] HDU4_ FIBERMAP BINTABLE Table with information about the targets ====== ========= ======== =================== FITS Header Units ================= HDU0 ---- EXTNAME = IMAGE 2D image with flat-fielded pixel values in electrons. Bias level and dark current have been subtracted. Electronic gains, converting ADC count to electrons have been applied. Pixel values have been divided by a pixel flat field. Additional corrections for some CCDs are electronic amplifier cross-talk correction, and negative trails corrections. The pre-scan and over-scan regions have been removed.

[1] Optional 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 :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``).
