==Correcting any logged data problems==
Some Weather stations may occasionally supply corrupted or rogue values to Cumulus.
Some rogue values may be obviously invalid (e.g. a zero pressure), others (e.g. wind shake on a tipping bucket rain gauge on a fine day) may be within the accepted all-time range, but you know the value is not right for that particular time.
You may choose to just edit the rogue value into a reasonable value, or (if you are unable to decide on a better value) to delete that particular entire row in the monthly log.
As explained above once any monthly log has been corrected, new highs and lows in other logs are easily rectified.
=== Spotting rogue values ===
===Manipulation outside Cumulus===
Any log files for ''previous'' months can be edited (outside Cumulus) with Cumulus running, and after editing them, you can do further fetch edits within Cumulus as described above. The current month log file can also be edited outside Cumulus, but as it is being updated frequently you must stop Cumulus first (that explains why there
'''Tips''' -- take a copy of the original log file before you work on it outside Cumulus (perhaps give the ''not to be touched copy'' a filename of "<Month><Year>log.csv").
===Using Monthly logs to deal with shorter (or incomplete) dayfile.txt records for particular dates===
'''WORKAROUND if dates are present in monthly log and dayfile.txt but not all fields for that date exist in dayfile.txt'''
Example: '''add extra fields to records created by an earlier version of Cumulus''' [to help you, the versions (not builds) at which fields were added are indicated below].
Second example: records imported prior to Cumulus processing them, so some calculated parameters (apparent temperature, heat index, rain rate, wind run) may not have been available from your weather station to insert in the log files.
