DESCRIPTION
whatatt computes the spacecraft attitude at a user-specified
epoch based on the contents of the attitude history file in
a given ODF. The ODF to use must either be pointed at by the environment
variable
SAS_ODF
or named via the generic command line parameters -o or
-odfdir (see taskmain
for
details). The specification of an ODF directory on the command line
has a higher precedence than any environment setting. The result of
whatatt is printed on standard output as a tuple
right-ascension/declination/astronomical-position-angle if
bstoolsout=false. Otherwise a command line for insbs is
generated.
