Some decision regarding convection of the output of the filter functions, based on discussion with @lepetersson and @JochenSeidel.

Meaning of flag values:

  • filter output is 1 for detecting an anomaly
  • filter output for functions stemming from the PWSQC R code is -1 in case the filter cannot be applied because not enough (non-NaN) data from neighbors
  • filter output is 0 otherwise

Data handling:

  • we write the flag time series to the xarray.Dataset as new variable
  • raw data is not changed
  • this way the user can decided, after generating/computing the flags, if all flags should be applied and how
