In order to consolidate the PHT calibration and verify its adequate application in OLP data reduction the following program is carried out: - observation of alpha Boo (Arcturus, HR 5340): star This is a well known calibration star with a consolidated spectral energy distribution. The star is sufficiently bright to be used as a standard at wavelengths longward of 60 micron. Since the star is very bright at the shorter wavelengths background observations are taken only for filters longward of 25 micron. Multi-filter scans are performed using all PHT filters available to the observers in AOTs P03 and P22. .HISTORY 31/01/97 IH, RJL, First version - Arcturus only (email UK to MFK 13/01/97) .OTT 3106 .TDT 3826
