This file controls the variables affected by contamination. In general it used by data.avg and similar programs that exclude contaminated data. It is located in $DB/etc/$STATION/contaminate.$STATION.conf or in the default location $DB/etc/contaminate.conf. If the station specific file does not exist then the default one is used.


Lines beginning with '#' are treated as comments. Each line consists of a start time as the first comma separated field followed by a list of patterns that define the variables affected by contamination from that time onwards or until another pattern set takes effect.

Full Perl regular expressions are accepted as the patterns and each is wrapped like “/^$pattern$/” when checked. So a pattern must match the entire variable name.

The start time can be omitted or set to “0” to specify that the given patterns take effect at the beginning of time otherwise any convertible time format is accepted.
