... By default the task will reduce the effective area produced in the ARF if the source area contains bad pixels/columns or contains area which lies outside the CCD boundaries. ... Although the correction for point sources is quite good the extended source correction assumes a uniform surface brightness of the source. ... There is currently no way of performing an accurate correction for chip gaps and bad pixels within extended source regions within arfgen . ...

... As described in "Tabular Storage of STIS Data" on page 20-5 , raw time-tagged Sdata are stored in an event table which contains separate columns for the x and y pixel coordinates and the arrival time of each detected photon event. ... Generate a series of ACCUMulated images from user specified time intervals of data and then process the image(s) with calstis . ... The default behavior for inttag is to accumulate all events from the table, writing the results as one image set in the output FITS file....

... This section describes three functions which have been created to cleanup defects in images. The first two functions for cleaning rows and columns are particularly useful for CCD--images. ... These can often be removed with the commands: MODIFY/COLUMN INPUT OUTPUT [C or V] [columns] . ... This is particularly useful for removing the permanent defects which may exist in the CCD--frames and which cannot be removed by the MODIFY/COLUMN or MODIFY/ROW commands. ...

SAOtng supports display of photon event data contained in raw files, similar to its support for FITS Binary Table extensions (e.g., X-ray event lists). ... Because event files do not usually contain enough information to generate an image, we have adopted some conventions for specifying how to interpret the data in these files and for how to bin rows of events into images. To image an event file, it is first of all necessary to define the structure of the events in the event file. ...
