FORS1 has been in operation from 1999-04-01 to 2009-03-31. The QC1 parameter database and the master calibration archive became operational in 2003. The QC1 parameters and the master calibrations of data generated in the first years of FORS1 operation have not been completely ingested into the databases. The following list shows for the available data for each type of FORS1 raw data type. Green dates mark data sets complete since the date mentioned in the table. Polarimetric data were not processed at all.
There are also master darks from 2000-05 to 2001-09 in the master calibration database.
zeropoint (per frame)
There are also zeropoint tables from 1999-11 to 2001-09 in the master calibration database. Standard star frames are available in the calibration database since 2005-05.
zeropoint (per night)
There are no products for the nightly zeropoints.
imaging screen flat
These data are used only for detector checks, not for processing .
imaging twilight flat
QC1 ingestion ended in April 2007.
MOS screen flat/arc
Since 2006-10 a new spectroscopic pipeline has been in use with much better results than before. Therefore previous spectroscopic calibration products were removed from the master calibration database
