NAME
vmifucalib - Generate IFU calibrations from a set of flat and arc lamp exposures.
SYNOPSIS
esorex vmifucalib [OPTIONS] FILE.sof
DESCRIPTION
This recipe produces the extraction mask, the wavelength calibration, and the relative
transmission correction, from a set of flat field and one arc lamp exposures (IFU mode).
Input files:
DO category: Type: Explanation: Required:
IFU_SCREEN_FLAT Raw Flat field Y
IFU_ARC_SPECTRUM Raw Arc spectrum .
LINE_CATALOG Calib Arc line catalog .
MASTER_BIAS Calib Master bias Y
IFU_IDENT Calib Fiber identification .
CCD_TABLE Calib Bad pixel table .
Output files:
DO category: Data type: Explanation:
IFU_MASTER_SCREEN_FLAT FITS image Stack of all raw flat fields
IFU_ARC_SPECTRUM_EXTRACTED FITS image Extracted arc spectra
IFU_FLAT_SPECTRUM_EXTRACTED FITS image Extracted flat field spectra
IFU_TRACE FITS table Extraction mask
IFU_IDS FITS table Wavelength calibration
IFU_TRANSMISSION FITS table Transmission correction
An arc spectrum exposure may not be specified in input, but in that case no wavelength
calibration nor fiber relative transmission correction will be computed, and further
reduction of associated scientific data will not be possible; the only products in this
case will be the stack of all the input raw flat field exposures, and the extraction mask.
If the arc spectrum exposure is specified in input, then also a line catalog must be
given. The fiber identification table, if given, ensures that all spectra will be safely
identified and assigned to the correct spatial position, but in most cases it will be
possible to reduce the data even without specifying this table in the input SOF. A CCD
table must be specified only if a bad pixel cleaning is requested.
For more details, please refer to the VIMOS Pipeline User´s Guide.
