Images Data, 3rd Edition, January 1994 The three CD-ROMs contain 3,935 images observed by the Imaging Proportional Counter (IPC) on the Einstein Observatory. The images have been smoothed and background subtracted, and are primary arrays, with ASCII extention tables for the detected source information. The data files conform to the FITS format for both images and tabular data. Relevant display software, auxiliary data files, and documentation are included on the discs.
Event List Format (Binary Data) This set of four CD-ROMS contains more detailed information, such as X- ray arrival time, photon pulse height bin, and full-resolution IPC pixel position, for each photon detected by the IPC and included in the IPC images in the CD-ROM set above. The data conform to the n-dimensional binary table extension (BINTABLE) to FITS that has been adopted by the U.S. ROSAT Data Center. Relevant display software, auxiliary data files, and documentation are included on the discs.
IPC Slew Survey (Binary Data) The IPC Slew Survey was constructed wholly from data acquired when the EO was slewing between one pointed observation and the next. The Slew Survey covers approximately 80% of the sky. This CD-ROM contains source lists, 1303 sky bin photon event data, auxiliary data, relevant analysis software and documentation. The sky bin data files conform to the n-dimensional table extension (BINTABLE) to the FITS format.
