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:

• $d$ represents the detector, i.e.:
  • C is for PHT-C.
  • P is for PHT-P.
  • S is for PHT-SS.
  • L is for PHT-SL.
  • G is for generic (not detector-specific)
• $t$ is a letter to identify the type of product. These are:
  • P is for point source photometry or spectroscopy in staring mode (single point or raster).
  • E is for extended source photometry.
  • I is for a photometric image.
  • U is for an uncertainty map.
  • T is for an exposure time map.
  • S is for raster photometry (including linear scans).

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.
