[PyCAMA] update filters for HCHO (possibly others) to exclude data with QA value < 0.5
Isabelle made a request to exclude retrievals with a QA value smaller than 0.5 from the PyCAMA analysis. At this moment we include everything that is not a fill value in the analysis, it is not hard to add a filter on the QA value, and start to monitor only the 'good' values. Please note that this also means that some problems may be masked by this choice, problems that only show up in retrievals 'with issues'. This is also the reason I haven't implemented this before. I will only implement this on request. The event counter will remain as is, but all retrievals with a small QA value will be removed here, if requested.
Let me know below if you want your product to be filtered, and in what way.
