"The CRL measurements at XRCF were performed with the HRC-I in focus and with no FAM motion. The absence of FAM motion limited the allowable rate and total exposure of the HRC-I. Beam flux was monitored by the 4 BND detectors near the input face of the HRMA. The count rate of these BNDs are linear up to rates >10 kHz."

"The lack of FAM motion ensures that the data are free of any systematics introduced by the FAM positioning system. This CRL data can then be used to determine the HRC-I/HRMA point spread function albeit with limited statistics."

"Count Rate Linearity versus BND rate is presented in the Figure(Postscript,GIF). The HRC-I/HRMA was illuminated with 2.56 keV X-rays from the DCM source. No evidence of nonlinearity over the limited flux values is evident."
