gbtmsfiller.setfixlags - Function



Package nrao
Module gbt
Tool gbtmsfiller


Toggle whether bad ACS lags should be fixed, if possible.


Synopsis
setfixlags(fixlags)


Arguments

fixlags   When true, bad ACS lags are fixed, if possible.
    Allowed: boolean
    Default: False


Returns
boolean


Description
The ACS some times suffers from bad 1024-lag segments where the entire segment is obviously offset and possibly scaled differently from the surrounding lags. If this toggle is true and that bad-lag segment is not the first 1024 lags, then the filler will "fix" the bad lags. This fix is done by first subtracting the median of those bad lags from the bad lags. Then the bad lags are scaled so that their standard deviation matches the standard deviation of the 512 lags on either side of the bad lags. Finally, a constant is added to the bad lags so that the median of the bad lags matches the median of the 512 lags on either side of the bad lags. If this toggle is false, the data are flagged as bad.
