As with LHO:85504 :: Even though I've fit for the transimpedance gain, I've elected *not* to include a gain in the foton design string relative to "ideal," as there are more scale factors in play that determine the overall [(meters)/(ADC cts)] scale in the calibration of the OSEMs (LED light power, PD response, any cable loss, ADC channel gain, etc.). Determining this overall scale is better left to different methods, a la LHO:84548, which we (eventually) anticipate doing for all SUS with ECR E2400330 upgraded satamps.
