There are two issues/changes needs to be addressed.\r\n1. In the current data collection protocol, we SUM a numbers of frames and save them to one tiff file. The SUM is done in the Area Detector plugins defining same number of images in the NDARRAY SUM. This limits us in having one file for each step of a temperature o other positioner scan. In some circumstances we might need several summed tiff files collected and saved at each STEP of the scan. We would like to have this flexibility integrated into the Ophyd. This protocol can me achieved using the Area Detector NDARRAY plugins. But need help to implement the same into Ophyd. The same protocol to be used for Dark Image. I have tested this protocol using Area-detector not through Ophyd, it works fine.\r\n2. The data type seems to be Int16 bit which limits to about 65K for the summed file. This might be a problem. We would like to change this to Float32."}}
