Common-user instrumentsThis page lists the FITS headers for NOT data obtained until March 2004 with the common-user instruments. See recent changes for keywords that were added to NOT FITS headers after March 2004. FITS keywords with an active link were added in 1999, others were already present at that time.The FITS headers are divided in 3 groups, image acquisition system (BIAS) information, telescope control system (TCS) information, instrument information. The FITS header contains blank lines before the 'END' keyword and between groups of cards. The TCS FITS headers are identical for all common-user instruments, the BIAS headers are very similar. In addition to these, the FITS header contains one of the instrument-specific blocks listed below. The ALFOSC fast-photometry mode uses non-standard image acquisition software which produces different FITS headers. Other instruments
