explain_xdata -- description of RDF files in PROS

INTRODUCTION

ROSAT data distributed in the rationalized data format (RDF) is an implementation of a Multi-Mission X-ray data format. RDF provides a common data format for ROSAT data processed by both the US and GERMAN data centers. Other high energy astronomy missions will also utilize RDF for their data format.

The RDF Basic FITS file is self-defining and supported in PROS by the QPOE data structure. Ancillary data such as orbit, aspect, and housekeeping data are provided in separate FITS bintable files. The ancillary data are supported in IRAF by the TABLES data structure. Postscript plots and Ascii outputs are also provided in FITS files.

PROS supports RDF and both US and German Rev0 formats. Data in all formats (RDF and PRE-RDF) are input into PROS using RFITS2PROS or RARC2PROS. For RDF the following files are created.

PSPC RDF


15 FITS files can be read by RFITS2PROS or RARC2PROS
----------------------------------------------------------------------------
