New for Postage Stamp Request Version 2

This page describes new features available in the IPP Postage Stamp server with version 2 of the request specification released 2013-05-02. A pdf of the specification is attached to PostageStampServer.

Request File Header

Two new keywords are defined for the header

ACTION string "PROCESS"

EMAIL string email of user submitting the request

ACTION is a new keyword that tells the system what to do with the request file. Users building and submitting their own request files should always set ACTION to "PROCESS".

The web interface will use other values for this keyword to trigger the server's "preview" mode.

EMAIL is used to track the user that submitted the request file. Users are encouraged to provide a valid value. (We promise no spam ;)

Request Table Columns

The most important new feature of Version 2 is the integration with the IPP's new release tracking system ipp_release_tracking. The IPP now has tables which clearly identify collections of runs with certain versions of the pipeline.

Two columns in the request specification are used to select images of interest using the release system.

SURVEY_NAME is a string used to select which survey from which to select images. Allowed values are the same as the PSPS survey definitions.

Note that at this time the release tables are only populated for 3PI, SSS, and the MD surveys.

IPP_RELEASE is used to specify a particular target release. If the user knows the precise reduction for a particular exposure or stack skycell this parameter is used. Note that if a particular release is not specified, the system will choose the "best" by preferring data from higher "priority" releases.

For example the most recent "grand reprocessing" of the 3PI survey is identified with the IPP_RELEASE 3PI.PV1. If a user requests stamps from a particular position on the sky, images will be selected from 3PI.PV1 for exposures that were included in that release. Images will be selected from the 3PI.nightly release for exposures that were observed after the processing for 3PI.PV1 was done.
