class SpectrumFold

The SpectrumFold monitor is designed to measure an excess in power at bins spaced at multiples of a given frequency (defaulting to 0.25 Hz) Running SpectrumFold The SpectrumFold command line syntax is:
SpectrumFold [-frames <number>] [-stride <time>] \
[-filter <filter>] [-settle <s-time>] [-dvIndex] \
[-f-start <freq>] [-f-stop <freq>] [-fold-length <freq>] \
[-channel <channel>] 
The <number> argument specifies the number of data strides to process before terminating the program. The <time> argument specifies the data stride. If "-dvIndex" is specified, a trend index file will be written to '\$DMTOUTPUT/channel.cnf'. -f-start and -f-stop specify the starting and ending frequencies of summation -fold-length specifies multiples of what frequency should be considered. -channel instructs SpectrumFold to add this channel to the list of monitored channels with parameter values specified just before this option. For example, -f-stop 1500.0 -channel H1:LSC-AS_Q -f-stop 300.0 H0:PEM_MIC1 will assign f-stop=1500 to AS_Q channel and f-stop=300.0 to microphone channel Configuration File SpectrumFold uses a fixed configuration. There is therfore no configuration file SpectrumFold Output Trend channels SpectrumFold produces a minute trend of all folded bins as well as SFT level. All channel names start with SpectrumFold Monitor data channels SpectrumFold publishes a time series history of the folded bins as well as average SFT level. All channel names start with SpectrumFold
