BND Analysis of HRC (Phase G) Data

There were six Beam Normalization Detectors (BNDs) used during the testing at the XRCF. Four of them were Flow Proportional Counters(FPCs) located around the perimeter of the AXAF High Resolution Mirror Assembly (HRMA). Two more, one FPC and a Solid State Detector (SSD), were located between the HRMA and the X-ray source.

In the following (postscript) memo we outline the process used for analysing the data taken by the four HRMA BND's (BND-H's):
