HRIIMAGE ivo://nasa.heasarc/hriimage NASA/GSFC HEASARC SAO; HEASARC 2026-06-12 NASA/GSFC HEASARC help desk heasarc-vo at athena.gsfc.nasa.gov Image The HRIIMAGE database table contains information from the High Resolution Imager aboard HEAO 2, the Einstein Observatory. Einstein incorporated a high-resolution X-ray telescope and a focal plane assembly capable of positioning at its focus one of four instruments: a high-resolution imaging detector (HRI), a broader-field imaging proportional counter (HRI), a solid state spectrometer (SSS), and a Bragg crystal spectrometer (FPCS). Einstein (HEAO 2) was launched on November 13, 1978, and operated successfully until April 1981. One duplicate entry was removed from the HEASARC implementation of this catalog in June 2019.
