13.4 AAR Product Types


13.4.1 Rationale behind product design

The AAR products represent fully processed data, therefore each AAR product reflects not only the PHT subinstrument used but also the mode of operation. The definition of products necessarily involves a compromise between a number of conflicting desires. The naming convention for PHT Auto-Analysis products is to use the product type $PdAt$, where:

The following table summarises the products that are associated with each AOT:

PHT03 PPAP, PPAE, PPAS, PGAI, PGAU, PGAT
PHT04 PPAP, PPAE
PHT05 PPAP, PPAE
PHT17/18/19 PPAP, PPAE
PHT22 PCAP, PCAE, PCAS, PGAI, PGAU, PGAT
PHT25 PCAP, PCAE
PHT32 PCAS, PGAI, PGAU, PGAT
PHT37/38/39 PCAP, PCAE
PHT40 PSAP, PSAE, PLAP, PLAE, PSAS, PLAS

In case of rectangular chopped observations, the spacecraft pointing is exactly in between the two chopper positions (see Sections 2.8 and 3.10). For these PHT specific observations, the general auto-analysis header contains the pointing keywords CONSCRA and CONSCDEC. These keywords give the actual source position of the on-source chopper beam.


13.4.2 Product PPAP

PPAP is the standard product for PHT-P photometry AOTs when observing a point source. It contains the flux densities for each of the filters and/or apertures used. 


  Origin:         PHT03, PHT04, PHT05, PHT17, PHT18, PHT19
  Units:          Jy
  Format:         FITS binary table file
  Limitations:    No colour correction performed.
                  Photometry with non-standard apertures is not scientifically
                  validated.
