Output Files

1. An OGIP-compliant Ancillary Response File, as defined in [3].

   This contains a table labelled ARF, that in turn contains:

   • A column labelled ENERG_LO, containing the lower bounds for each energy bin (keV).
   • A column labelled ENERG_HI, containing the upper bounds for each energy bin (keV).
   • A column labelled SPECRESP, listing the area for each energy bin described by the ENERG_LO and ENERG_HI columns.

   and the following attributes:

   • TELESCOP
   • INSTRUME
   • FILTER
   • ARFVERSN
   • HDUCLASS
   • HDUCLAS1
   • HDUCLAS2
   • HDUCLAS3
   • HDUVERS1

2. A intermediate and temporary dataset containing the input detector map in pixel list form. used as input to attcalc to compute the detector-sky coordinate conversion.

   This contains a table labelled EVENTS, which in turn contains:

   • A column labelled VALUE of type real-64
   • A column labelled X of type int-32
   • A column labelled Y of type int-32
   • A column labelled DETX of type int-16
   • A column labelled DETY of type int-16
   • A column labelled TIME of type real-64

   and the following attributes:

   • TELESCOP
   • INSTRUME
   • DATAMODE

3. A version of the input detector map, in pixel list form, filtered using the DSS information stored in the spectrum dataset. This is written out as a permanent dataset with a name corresponding to filteredset if withfilteredset is set to true.

   This contains a table labelled EVENTS, which in turn contains:

   • A column labelled VALUE of type real-64
   • A column labelled X of type int-32
   • A column labelled Y of type int-32
   • A column labelled DETX of type int-16
   • A column labelled DETY of type int-16
   • A column labelled TIME of type real-64

   and the following attributes:

   • TELESCOP
   • INSTRUME
   • DATAMODE

4. Miscellaneous temporary files

   Temporary files are used to store data used to calculate the effect of bad pixels and chip gaps on the final ARF. These have unique filenames of the form

   • temp_badcol.XXXXXX
   • OFFSET.XXXXXX
   • BSMAP.XXXXXX
   • rawpixellist.XXXXXX

   where XXXXXX is a random alphanumeric 6 character string. These will be removed automatically on successful program termination unless the parameter withfilteredset is set to true.
