STATDUMPFREQ in RING-DEFINITION

It seems that the option STATDUMPFREQ does not work as expected in OPAL-C - Ring Definition. The statistics dumped in the .stat file depends on the PSDUMPFREQ normally used for the h5.

Example

For a certain beamline, the expected RMSX is: ExpectedRMS.

The plot is obtained from the .stat file (column 2 and 6) and with the following options set in the OPAL input file

OPTION, PSDUMPFREQ=10;
OPTION, ENABLEHDF5=FALSE;
OPTION, TELL=TRUE;
OPTION, PSDUMPFRAME=BUNCH_MEAN;

The STATDUMPFREQ is not specified, so the default value STATDUMPFREQ = 10 should be used.

With the following options:

  • reducing the PSDUMPFREQ
OPTION, PSDUMPFREQ=100000000;
OPTION, STATDUMPFREQ = 10;
OPTION, TELL=TRUE;
OPTION, PSDUMPFRAME=BUNCH_MEAN;
  • disabling the .h5 files but with high PSDUMPFREQ
OPTION, PSDUMPFREQ=10;
OPTION, ENABLEHDF5=FALSE;
OPTION, TELL=TRUE;
OPTION, PSDUMPFRAME=BUNCH_MEAN;

the RMSX from the generated stat file is: STATDUMP

The result does not change if the STATDUMPFREQ is specified in the input file or not.

Any suggestions?
