NAMEvmdet - Determine RON, gain, and bad pixels from a set of flat field exposures.
SYNOPSISesorex vmdet [OPTIONS] FILE.sof
DESCRIPTIONThis recipe is used to estimate the read-out-noise (RON) and the gain of the CCD, and to determine the positions of the bad pixels. The input SOF should contain at least five pairs of flat field exposures, all belonging to the same quadrant, each pair corresponding to a different exposure time. The flat fields can be produced either in imaging or in MOS mode. In MOS mode a HR grism is used, in order to illuminate the CCD also beyond the central region used in direct imaging mode, but no mask is inserted at the telescope focal plane. This type of exposure cannot really be considered a spectral flat field, because the CCD is exposed to white light (i.e., without a wavelength dependency along the dispersion direction). The flat fields generated for the purpose of determining the detector proper‐ ties are assigned the DO category DETECTOR_PROPERTIES, to distinguish them from the more common IMG_SCREEN_FLAT or MOS_SCREEN_FLAT that are used to produce master calibrations. Input files: DO category: Type: Explanation: Required: DETECTOR_PROPERTIES Raw Flat field Y MASTER_BIAS Calib Master bias Y Output files: DO category: Data type: Explanation: CCD_TABLE FITS table Bad pixel table (none) FITS image Bad pixel image (none) FITS image Error image Only the primary product, the bad pixel table, is copied (or moved) to the product direc‐ tory. Other products are generated only on request (typically for debug purposes) and are not assigned a DO category as they would not be used anywhere in further data processing steps. For more details, please refer to the VIMOS Pipeline User´s Guide.
OPTIONS--CreateBadPixelMap <bool> Bad pixel map creation (bool; default: True). The full name of this option for the EsoRex configuration file is vimos.Parameters.map [default = True]. --CreateErrorImage <bool> Response slope uncertainty map creation (bool; default: False). The full name of this option for the EsoRex configuration file is vimos.Parameters.error [default = False]. --DetectionThreshold <float> Threshold in determination of bad pixels (float; default: 5.0). The full name of this option for the EsoRex configuration file is vimos.Parameters.threshold [default = 5.0]. --DetectionMode <str> Bad pixel detection method (str; default: ´Intolerant´). The full name of this option for the EsoRex configuration file is vimos.Parameters.method [default = Intolerant]. --ComputeQC <bool> Compute QC1 parameters. (bool; default: True). The full name of this option for the EsoRex configuration file is vimos.Parameters.quality.enable [default = True]. Note that it is possible to create a configuration file containing these options, along with suitable default values. Please refer to the details provided by the 'esorex --help' command.
