This is a simple imaging programme consisting of both narrow and intermediate-band imaging of two fields. Each science OB has a name which indicates the field , the pointing, the filter (med, n1, n2 or n2) and the frame numbers with respect to the dithering sequence. Since there are two dithers (i.e. exposures) per OB, these numbers go in pairs: 1-2, 3-4, 5-6, etc. The filter names refer to the filters med=815 medium, n1=810 narrow, n2=817 narrow, n3=824 narrow. Sky and dome flat calibrations have been supplied since all of the filters are non-standard, and therefore not a part of the Standard Calibration Plan. ! Time Critical Aspects: If possible, the medium band (med 815 filter) observations of the AXAF field should be spread over the same nights which the other two filters are used. However, this is not crucial if it can not be done for some reason.
