vmimpreimaging: Reduce a preimaging science exposure.

SYNOPSIS

esorex vmimpreimaging [OPTIONS] FILE.sof

DESCRIPTION

This recipe is used to apply basic reduction steps to the imaging observation that is preliminary to a MOS observation of the same field. No source detection is attempted on the image. The image WCS, together with the component describing the instrument optical distortions, is converted into the convention followed by VMMPS (the VIMOS mask preparation software). This set of coefficients, the so-called CO-matrix used by the SAO WCSTools package, is written to the header of the reduced image.

Input files:

  DO category:              Type:       Explanation:         Required:
  IMG_PREIMAGING            Raw         Preimaging exposure     Y
  MASTER_BIAS               Calib       Master bias             Y
  IMG_MASTER_SKY_FLAT       Calib       Master sky flat         Y
  PHOT_COEFF_TABLE          Calib       Photometric table       .

  CCD_TABLE                 Calib       Bad pixel table         .

Output files:

  DO category:              Data type:  Explanation:
  IMG_SCIENCE_REDUCED       FITS image  Reduced preimaging exposure

If a photometric table is specified, the magnitude zeropoint, the atmospheric extinction coefficient, and the colour term are copied from the photometric table to the header of the reduced image. A CCD table must be specified in input only if a bad pixel cleaning is requested.

For more details, please refer to the VIMOS Pipeline User\'s Guide.

OPTIONS

--BiasMethod <str>: Bias removal method. (str; default: \'Zmaster\'). The full name of this option for the EsoRex configuration file is vimos.Parameters.bias.removing.method [default = Zmaster].
--CleanBadPixel <bool>: Bad pixel correction on reduced science image. (bool; default: False). The full name of this option for the EsoRex configuration file is vimos.Parameters.badpixel.clean [default = False].
--CleanCosmic <bool>: Cosmic ray removal from the input science image. (bool; default: True). The full name of this option for the EsoRex configuration file is vimos.Parameters.cosmics.clean [default = True].
--CosmicsThreshold <float>: Threshold for cosmic ray candidate selection. (float; default: 4.0). The full name of this option for the EsoRex configuration file is vimos.Parameters.cosmics.threshold [default = 4.0].
--CosmicsRatio <float>: Ratio for discrimination of objects and cosmics. (float; default: 2.0). The full name of this option for the EsoRex configuration file is vimos.Parameters.cosmics.ratio [default = 2.0].
--TemperatureCheck <bool>: Check beam temperature when updating the world coordinate system. (bool; default: True). The full name of this option for the EsoRex configuration file is vimos.Parameters.temperature.check [default = True].
--TemperatureTolerance <float>: Maximum allowed difference between beam and ambient temperature. (float; default: 3.0). The full name of this option for the EsoRex configuration file is vimos.Parameters.temperature.tolerance [default = 3.0].

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.
