Purpose: Cast an event images in sky coordinates using the
ACTIME.DAT accepted times file. The data are cast in pixels which match
the detector maps and therefore the exposure maps. The pixel size is
.
File Input:
1) Observation data set fits files - xxx_EVENTS.FITS for German
or US data, xxx_BAS.FITS for RDF data.
2) Other fixed input - ACTIME.DAT modified as desired. For US and RDF
data, each of the programs will create this file if it does not exist. For
German data sets, the data must be taken from the xxx_EVENTS.FITS header
information (see section on VALID_TIMES). This ACTIME.DAT file must be
the same time selection as used with the programs CAST_EXP_HRI, and
CAST_PART_HRI.
Interactive Input:
1) Observation control - the eight or fewer character string listed above
as xxx.
2) Data format control - 1 for German data, 2 for US data,
3 for RDF data.
3) Nominal pointing direction - the nominal pointing direction (in decimal
degrees) taken from the observation data set hard copy or the
header information of the observation data set fits files.
Screen Output:
1) Diagnostic output - number of events.
Image Output:
1) Fits file of observed events: counts.fits.
