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.
