FOS/BLUE Wavelength-Zeropoint Correction Procedure Summary: A significant time-dependent systematic shift of up to 7 quarter-stepped pixels (1.75 diodes) in the zero-point of the FOS/BL wavelength scale has been confirmed in FOS Instrument Science Report (ISR) CAL/FOS-149 (Rosa, Kerber, and Keyes). ... Figures 1 and 2 (PDF - 14 Kbytes) illustrate the magnitude of the observed shifts and the effectiveness of the quick-fix algorithm provided here. ...

... The RA and Dec coordinates are computed using the pointing direction of the OM camera as the origin, and because the RA and Dec coordinates of this point may not be exactly the same as the coordinates deduced from reference to a catalogue (differences of a few arcsecs in RA and Dec are typical), omsrclistcomb (in a similar fashion to omatt ) allows the user to determine these shifts and correct the source positions. ...
