Pipeline Product Data - Summary Files and Groupings

The Pipeline Processing (PP) produces quite a number of useful products which allow a first look at the data, but can overwhelm the user by their sheer numbers. The first place to look is the INDEX.HTM page which organizes the presentation of the data and provides links to other PP pages. The INDEX.HTM page also lists general observation information (target, date, time, etc.) and instrument modes.

The INDEX.HTM page provides links to various observation summary pages, which have names with the following nomenclature:

PP data contain some immediately useful data products such as calibrated photon event lists, source lists, and images. While there are a large number of products which come in a single directory, they can be associated in up to 15 groupings; see Table 5.2. (The number of groups can vary depending on the number of operational instruments, e.g., if the OM is turned off there are no OM products.) Further information on each of these groupings and associated files, such as file contents, file types, and how they may be viewed, can be found in Table 5.3. Each group has an associated HTML file which organizes access to the files and provides a limited description of them. The names of the HTML files are of the following form:

Group ID Contents
  PP files
PPSDAT Contains the Calibration Index File (CIF) used in the pipeline processing (*CALIND*),
  PPS information, and the attitude history time series (*ATTTSR*) in gzipped FITS
  or ASCII format.
PPSGRA Contains the OM tracking history plots, PPS, EPIC, OM, RGS observation, and PPS
  run summaries. NOTE: CHECK THESE OUT
PPSMSG ASCII file containing pipeline processing report
  EPIC files
CRSCOR Contains PDF files of POSS II finding charts, HTML files of cross correlations
  with the SIMBAD data base, FITS tables for the detected sources
EANCIL Contains the exposure maps in a variety of energy bands and the source-detection
  sensitivity maps for the EPIC instruments. The sensitivities are in units of
  counts s$^{-1}$ corrected for vignetting and corresponding to a likelihood specified
  in the FITS header. The files are gzipped with a .FTZ extension.
EEVLIS Contains calibrated photon event files for the EPIC detectors. If the files are
  sufficiently large they may be separated into two tar files. The files are gzipped
  fits files with a .FTZ extension.
ESKYIM This group contains the event images in a variety of energy bands. The fits files
  are gzipped with a .FTZ extension, the full images also come as PNG images.
ESRLIS Contains EPIC observation source lists. There is an HTML page of the merged
  source list and gzipped fits tables of source lists from the different instruments
  and source detection tasks.
  OM files
OIMAGE Contains OM sky images in gzipped FITS format.
OMSLIS Contains OM observation source lists in gzipped FITS format.
OMSRTS Contains OM star tracking time series in gzipped FITS format.
  RGS files
REVLIS Contains the RGS source and event lists in gzipped FITS format
REXPIM Contains the RGS exposure maps in gzipped FITS format
RIMAGE Contains the RGS images (both energy dispersion and cross dispersion) in gzipped
  FITS and PNG formats
RSPECT Contains the RGS source and background spectra in gzipped FITS and PDF formats
