This accession consists of Assignment/Support Requests. For projects funded through the Smithsonian Astrophysical Observatory (SAO), the mechanism for formally requesting engineering support is to submit a form called an "Assignment/Support Request" (ASR). An ASR functions both as an internal purchase order for engineering services, and as a planning document for engineering management. It serves the SAO Controller's Office as a funds obligation document, and the project Principal Investigator or Program Manager as a vehicle both for describing the engineering support required, and for negotiating specific staff assignments and project schedules with the Engineering Manager.
In addition to the ASR materials there are schematics and drawings of NASA's Chandra X-Ray Observatory (formerly the Advanced X-ray Astrophysics Facility or AXAF) and the High Resolution Camera (HRC) developed for it. Both the AXAF and HRC were projects SAO worked on. For related materials please see Accessions 05-007 and 06-075. Some materials are in electronic format.
