Tables

Midas tables are used to store most the information created and/or used by the MOS context. The tables MOS, LINPOS, LINFIT and WINDOWS are created by the MOS commands; the tables LINECAT and STANDARD are available in the Midas data base. A short description of the tables is given below; a detailed description of their contents can be found in Table .

MOS.tbl

is created by LOCATE/MOS and used during the whole reduction process. It contains the limits of the slitlets.

LINPOS.tbl

is created by SEARCH/MOS and updated by CALIBRATE/MOS. It contains the pixel-positions of the calibration lines, the row and the slitlet they belong to, their identifications and their intensities.

LINFIT.tbl

is created by CALIBRATE/MOS and used by REBIN/MOS. It contains the fit coefficients for the dispersion relations of each row scanned by SEARCH/MOS.

WINDOWS.tbl

is created by DEFINE/MOS and used by FITSKY/MOS and by EXTRACT/MOS. It contains the positions of the objects and the sky regions.

LINECAT.tbl

contains the wavelength calibration lines. There will be several line-catalogs available in the instrument related system area, adapted for the use with the FORS grisms.

STANDARD.tbl

contains the fluxes of standard stars in different units. These tables will be copied automatically from the area MID_STANDARD into the user's work space by SET/MOS FLUXTAB=name.
