CMDB Issues

CMDB summary sheets are available here. These summaries show total number of measurements sumitted in teach CMDB and the number that will fit in the allotted time, based on an efficiency-based ordering scheme. The summaries also show statistics on configuration overhead, measurement priority, and X-ray source utilization.

Phase 1 Rehearsal taught us a lot of lessons about reviewing and using the CMDB. Please follow this link to a description of the Measurement Submission Procedure.

The Calibration Measurement List Interface Control Document

This web page contains the description of the contents of each field in the CMDB. AKA, XC05 Book II Appendix C. Authored by Hank Donnelly at the ASC.

The ASC Measurement Script Expander

This web page describes the tool developed by the ASC to turn a human-digestible suite of measurements into the Cal Working Group CMDB Format. The expander makes every column in the CMDB, save one: Measurement Time. Measurement time is supplied in the last column by the Timing Simulator.

The ASC Timing Simulator

The Timing Simulator uses the CMDB's parameters and integration times to calculate intra-measurement overhead time, overhead internal to a measurement due to HXDS moves, dithering, shutter changes, etc. By adding this overhead to integration time, the Timing Sim supplies Measurement Time to the last column of the CMDB.

Amelia, the TRW Anonymous FTP Site

During rehearsal and calibration, the CMDB mainly exists on the XRCF Lan, and is not directly available to the outside world. At other times, the ASC supplies revised CMDBs to TRW via the TRW anonymous FTP site.

"However, we are plowing through every possible three letter combination of the code. But since there are, ah, seventeen thousand permutations, um, its going to take us about two and a half days to transmit them all."

"How soon did you say the planes would penetrate Russian radar cover?"

"About eighteen minutes from now."
