XTEPUBLIC: Help

==> xtepublic.html <==

XTEPUBLIC: RXTE Archived Public Data


Overview

The XTEPUBLIC table is based on information culled from the RXTE Data Archive's latest top-level FMI (FITS Master Index) file that is created when data products are made publicly available each week. ObsIDs listed in this table are available for download from ftp://legacy.gsfc.nasa.gov/xte/data/archive/. See the parameter data_loc for the exact location of specific ObsIDs. No slew ObsIDs are listed in this table. If you are interested in slew data, please refer to the XTESLEW table.

Description

The XTEPUBLIC table is updated automatically on a weekly basis whenever the RXTE GOF updates the top-level FITS Master Index (FMI) file for the public data archive and notifies the HEASARC.

Parameters

obsid
  The observation's unique identifier.

cycle
  XTE cycle (AO phase) number to which the observation belongs.
  IOC observations have cycle = 0.

prnb
  Proposal number of the observation.

target_number
  Target number of the observation in the proposal.

event_flag
  The type of event associated with the observation where:
  • A = slew before observation (available for public)
  • S = raster scan observation
  • Z = slew after observation (available for public)
  • 0-9 = parts of an observation that's broken into shorter pieces
  • B-R = (potentially) realtime changes in configurations
start_time The time the observation started. stop_time The time the observation stopped. pi_name The name of the principle investigator for the XTE Observation Request. target_name The name of the source or target of the observation. ra Right ascension of the target. dec Declination of the target. lii Galactic Longitude of the target. bii Galactic Latitude of the target. data_loc If the data is stored on-line, the path to the directory will be at <URL:ftp://legacy.gsfc.nasa.gov/xte/data/archive/data_loc>.

Data Products Categories and Descriptions

The XTEPUBLIC table has the following data products categories defined:
  • Complete Data Directory of a Single XTE Observation (FULL OBSID)
    This set contains the entire ObsID directory for each selected observation. The ObsID directory contains all the data products for each observation.
  • Standard Products (including GIFs) of a Single RXTE Observation (STDPRODS)
    Same as FULL OBSID except it contains only the "stdprod" subdirectory in the data directory for each selected ObsID. The processed GIFs are also included since they are in a subdirectory under the "stdprod" directory.
  • GIF Standard Products of a Single RXTE Observation (GIFS)
    Same as STDPRODS except it contains only the "GIFS" subdirectory under the data directory for each selected ObsID.
  • PCA Summary Quicklook GIFs of a Single RXTE Observation (SUMMARY GIFS)
    A subset of the GIFS category consisting of just two GIFs: the PCA Net Cleaned Light Curve and the PCA Net Cleaned Spectrum.
  • Merged Lightcurves (MERGEDPRODS)
    This category contains lightcurves in FITS and GIF formats constructed by combining all of the observation data from the specified proposal for each target. Thus, these products are derived from multiple ObsIDs usually. If the time period in which the observations were made spans more than one detector gain epoch, then there will be separate lightcurves for each epoch.
