Source of the spacecraft attitude information

There are three allowed sources of this information, governed by the parameter attsource:

  1. attsource=`binned': the binned attitude output of attbin is read from the file inbinnedattset.

  2. attsource=`odf': the attitude information stored in the ODF is used. (Note that the user must set the environment variable SAS_ODF to point to this ODF before running evproject in this mode.) If parameter odfattsource is set to `ahf', the Attititude History File of the ODF is the source of the attitude values; if it is set to `om', the values are read from the OM tracking history file.

    The task bins up these attitude values, as described in section 3.6; the binned-up attitude values may be exported to a file via parameters writebinnedatt and outbinnedattset. Tasks eootemap, epnoisemap, eimchip2sky and eexpchipmap are designed to be able to read this binned-attitude dataset, so that they can use the same binning scheme as evproject.

  3. attsource=`fixed': the attitude is taken from user-supplied values via parameters attra, attdec and attapos.

Note that the source chosen for attitude data affects the calculation of the PNT keywords (see next section).
