... It lists the coefficients defining the colour transformations, the zero points for the different filters and the aperture radii used in the photometric calibration analysis. ... The AB system zero point of the filter FilterID is stored in the keyword ABM0 FilterID , e.g. the AB zero point of the the U-filter is stored in ABM0U. The flux conversion factor derived from White Dwarfs of the filter FilterID is stored in the keyword FCF FilterID . ... description . ... AB Flux conversion factor of U . ...

... All STIS data products are FITS files. Images and two-dimensional spectroscopic data are stored in FITS image extension files, which can be directly manipulated, without conversion, in the IRAF/STSDAS environment. These FITS image extension files allow an associated set of STIS science exposures, processed through calibration as a single unit, to be packaged into a single file. ... A triplet of FITS image extensions corresponds to each exposure in a STIS data file: . ... array . ...

Next: Specifying Pixels in Up: MIDAS Data Structures Previous: Specifying Keywords . The MIDAS table file system is described in detail in chapter 5 of this volume. Here we just explain briefly how to access the various elements in a table file. To do so, it is necessary to specify the table name , the column and the row . ... table,column,row = value , e.g. to set the element in the 3rd row of the column labeled :XREF in the table lola.tbl to 1.234 , use lola,:xref,@3 = 1.234 . ...

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. ...
