Stack batches

PSPS loads both nightly and deep stacks from the IPP. For deep stacks, two extra tables are produced: StackApFlx and StackModelFit. The input for both are IPP cmf files produced at the stack stage of the pipeline. One FITS output is generated by the interface per skycell, per filter.

PSPS tables

1 Primary extension
1 StackMeta extension per skycell
1 StackDetection extension per skycell
1 StackToImage extension
1 SkinnyObject extension
1 ObjectCalColor extension

Deep stacks have two extra extensions.

1 StackApFlx extension per skycell
1 StackModelFit extension per skycell

The full table definitions can be seen here

Current IPP to PSPS mappings

The tables below detail the current mapping between IPP and PSPS. The source of cmf files queued by ippToPsps is a list of sky_ids that are loaded into the relevant DVO database. These sky_ids are then used to obtain metadata from the IPP GPC1 database, as well as the location of the cmf file themselves. For more information on the fields listed below, see also the following links:

• description of psphotStack
