NAME

rslctsfluct - Calculate CTS Control and Monitor thermometer temperature fluctuations

USAGE

rslctsfluct infile outfile

DESCRIPTION

The rslctsfluct task calculates the temperature read-out fluctuations of the calorimeter thermal sink (CTS) ADR control and monitor thermometers from a Resolve housekeeping input file, and populates columns in a Resolve housekeeping output file with the results.

There are four CTS thermometers, with two operating - one as the control, and one as the monitor thermometer, at any one time. These are identified for each row according to the the values in the four temperature columns (these are set to -1 for the redundant thermometers) specified by the 'st1ctl1col', 'st1ctl2col', 'st1ctl3col', 'st1ctl4col' parameters; and, by the proportional-integral-derivative (PID) controller setting stored in the column specified by the 'pidselcol' parameter. Rows where the PID control is not operating are identified by the value of the column specified by the 'pidselcol' parameter. For these rows, both control and monitor fluctuation columns are set to the value specified by the 'nullnoctrl' parameter.

The fluctuations are calculated for each row by calculating the standard deviation of the control and monitor temperatures described above over a sliding window of nominal size specified by the 'winsize' parameter. If all values in the window are identical, the fluctuations columns are set to the value specified by the 'nullstatic' parameter. The window is centered on the time of each row stored in the column specified by the 'timecol' parameter. At the beginning and end of the file, the fluctuation calculation proceeds over a window reduced in size accordingly, provided it is larger than the value given by the product of 'winsize' and 'filfacmin'. Otherwise, both control and monitor fluctuations columns are set to the value specified by the 'nullfilfac' parameter.

Output column used to store MON fluctuations.

(winsize = 120.0) [double]
Window size used to calculate fluctuations [s].

(filfacmin = 0.5) [double]
Minimum filling factor used to calculate fluctuations.

(nullstatic = -120.0) [double]
Null value used if HK temperature readings not updating [microKrms].

(nullfilfac = -110.0) [double]
Null value used if window smaller than filfacmin [microKrms].

(nullnoctrl = -100.0) [double]
Null value used if PID control not operating [microKrms].

(buffer = -1) [integer -1|0|N]

(clobber = no) [boolean yes|no]
Overwrites the existing output file if set to yes.

(chatter = 1) [integer 0|1|2|3]
Chatter level for output. Set to 0 to suppress output, or to 1, 2, or 3 for increasing the chatter of the output.

(logfile = !DEFAULT) [string DEFAULT|NONE|file name]
