Counting mode check

This check identifies the time intervals when any of the EPIC instruments is in counting mode. This is done by looking at the counting cycle report data in the ODF. The following anomalies are detected and lead to a warning:

• A counting mode interval appears from the data to have a negative duration.
• A counting mode interval appears to have lasted longer than the exposure it belongs to.

These anomalies usually point to problems with the creation of the ODF.
