Returns the value of the query expression stored in the CALDB structure.
String_Type calGetQuery( Caldb_Type cal )
This function returns the value of the
query expression field in the CALDB structure.
This field is used to define the boundary conditions
when querying the CALDB; if no such condition has been
specified then either "-" or "" is returned.
The caldb module is not available by default; to use it in a
S-Lang program, it must be loaded using the
S-Lang require() function:
variable cal = calCreateInfo( "img.fits" );
variable expr = calGetQuery( cal );
if ( orelse { "" == expr } { 0 == strcmp( "-", expr ) } )
message( "No boundary condition has been set up." );
