  "description": "This is the Einstein Observatory 2E Catalog of Imaging Proportional Counter (IPC) X-Ray Sources which was created by the HEASARC from the CDS Catalog IX/13. This latter catalog was prepared by the CDS in October 1996 based on the Einline version. It is similar to the HEASARC's IPC source catalog which the HEASARC created in the early 1990s directly based on Einstein Observatory Source Catalog tables obtained from the then-extant Astrophysics Data System distributed data archive. The IPC Catalog contains 6816 entries compared to 5948 entries in this catalog, notice. This catalog contains sources with signal-to-noise values of 3.5 and greater from Einstein IPC observations. Note that a single source may have more than one entry in this catalog. This catalog was created by the HEASARC in November 2000 based on the <a href=\"https://cdsarc.cds.unistra.fr/ftp/cats/IX/13\">CDS Catalog IX/13</a> file 2e.dat. This is a service provided by NASA HEASARC .",
