Subject: JEMX1/JEMX2 relative count rate Dear Silvia, During last weeks SDAST-meeting Peter asked me to send you my calibration of the relative JEMX1/JEMX2 count rate in revolution 17. I used the scw's listed below and found An average ratio, JemX1/JemX2 = 1.04 +/- 0.02 (3-12 keV). Staring obs of Cyg X-1.
