NAME
wslew -- Process eventdata during recorded during slewing
to produce instrument pointing and countrates per timebin.
USAGE
wslew infile attfile outfile bintime [optional parameters]
DESCRIPTION
Eventfiles are processed so that it can the actual countrates
over the detector can be calculated. To exclude the counts of the
In-Flight Calibration sources filtered files should be used.
PARAMETERS
infile [string]
The name and extension number in square brackets of the input
FITS table extension containing the list of events to be
filtered. If no extension is given the complete file with all
its extension will be processed.
attfile [string]
Name of the input attitude FITS file needed for calculating
the actual instrument poinintg
outfile [string]
Name of the resulting FITS file containing per timebin
the event flux and instrument pointing.
bintime [real]
The time in sevceonds per accumalation of eventrates.
(calfile1=" ") [string]
The name of the input FITS file that contains among others
the misalignment angles to calculate the instrument pointing.
(calfile2=" ") [string]
Same as for calfile1, only used for SAX WFC-2.
(tcolumn="WFC_TIME") [string]
The name of the column in INFILE that contains the time stamp
value that is used to determine if that row falls within one of
the input Good Time Intervals. The values in this column
should be in units of seconds relative to the start time ??
specified by the obsdate and obstime keywords in the header of
the extension.
(obsdate="-") [string]
The name of the keyword containing the reference date in the
input events table. The value can either be blank (or "-") to
defeat the reference checking, in julian days or in 'dd/mm/yy'
format.
(obstime="MJDREF") [string]
The name of the keyword containing the reference time in the
input events table in 'hh:mm:ss.ddd' format. This parameter is
only used if obsdate is in dd/mm/yy format.
(obsunit="T_UNIT") [string]
The name of the keyword containing the units of the time column.
If omitted unites of 1 second are assumed.
(copyall=yes) [boolean]
If the copyall parameter is set equal to 'NO' then the output
FITS files will consist of a null primary array followed by a
table or bintable extension (depending on the type of the input
extension). If copyall equal YES, then the primary array and
any other extensions in the input file will also be copied to
the output file.
(verbsty=0) [integer]
The verbosity level will control the output volume.
EXAMPLES
1. Analyze one attitude file and produce one pointing file
--> wslew OBS_srn1 OBS_att1 OBS_ssl2
METHOD
REMARKS
- The should be extended to provide a deadtime corrected
countrates.
