Changeset 36645 for trunk/PS-IPP-PStamp/lib/PS/IPP/PStamp/Job.pm

Message:

For bycoord and byskycell requests for warps using releasetool add a wide coordinate
cut (5 degree distance from center to boresite) on the command line. This greatly
reduces the query time by reducing the number of warpRuns and thus warpSkyfile's rows joined.
