***** File CR_CALIB.TXT This directory contains supplemental data submitted to the P/Crommelin archive by the Infrared Studies (IRSN) and Spectroscopy (SSN) Networks. The IRSN contribution consists of eight Filter Tables. Each observation file refers to one or two of these filter tables (cf. the column FLTRTABL in the Table Data records of the observation files and the keyword DIS-CODE in the FITS headers of the Filter Tables). The SSN contribution consists of seven files of standard star observations. A table linking these standard star observations to the appropriate P/Crommelin observations is given below: Calibration System Calibration Date(UT) Time(UT Associated Filename Code Object day fr.)
