As we move to higher rates we are thinking of ways we can support “integrating detectors”, e.g. a slow 1Hz camera running with a 1MHz high-speed detector (e.g. hsd) where you need to analyze precisely all 1MHz shots that contributed to the slow image (assuming that the slow device’s “shutter" is precise, which is likely not true for all devices … that’s a separate issue).

With psana parallelization (necessary for high-rate analysis) it will be difficult for us to support arbitrary integration periods for multiple detectors, e.g. detector1 integrating over shots 1,2,3 (and 4,5,6) while detector2 integrates over 1,2,3,4 (and 5,6,7,8).  We think we can support multiple detectors with one integrating at a “highest harmonic” (e.g. 1,2,3 then 4,5,6) and another simultaneously integrating in the same way, or at an integer “lower harmonic" (e.g., 1,2,3,4,5,6 then 7,8,9,10,11,12)

My question: can you let us know if you foresee that the above “highest harmonic” requirement would not be sufficient for your experiments?
