The HEASARC welcomes your participation in a brief survey to capture how users access and utilize HEASARC data, software, and services. The outcome(s) of this survey will be used to guide, prioritize, and plan our activities and development in the coming years. It contains 20 questions, generally takes just a few minutes to complete, and your answers will remain totally anonymous. The survey is open until Dec 18, 2023. We thank you in advance for your valuable feedback.

ASCA Guest Observer Facility

ASCA Public Archive Complete

October 5th, 2001.


Between 1993 Apr 5 and 2000 July 15, ASCA performed 3079 separate observation sequences. These are now all publicly available at the HEASARC, and can be accessed using the "ascamaster" catalog in Browse.

All data have been processed using revision 2 data processing. We currently plan to re-process all ASCA data within the next year or so. The main purpose of this will be to incorporate the final calibration of time-dependent gains of both the GIS and the SIS; we do not anticipate major changes in the directory structure or in the type of data products.
