CalFUSE gives warnings about the detector voltage changing during an exposure, but the data look OK to me. Is this something that I should be worried about?
If the header keywords indicate that the detector voltage was high, low, or changed during an exposure, CalFUSE writes a warning message to the trailer file. If a valid housekeeping file is available for the exposure, this warning may be safely ignored, because the pipeline uses housekeeping information to populate the high-voltage array in the timeline table and properly excludes time intervals when the voltage was low. If the housekeeping file is not present, each entry of the high-voltage array is set to the “HV bias maximum setting” reported in the IDF header. In this case, the pipeline has no information about time-dependent changes in the detector high voltage, and warnings about voltage-level changes should be investigated by the user.
