Cryogenic Systems Operation
The CryoBay logs data to the host at a default rate of once
per hour when VnmrJ is running. In the event of a fault,
finer resolution data may be uploaded to the host by the
user. The log files have a header line followed by lines of
tab- separated values. They can be imported into an
OpenOffice Calc spreadsheet with "Insert / Sheet from File",
specifying "tab" as the only field delimiter.
Data files are stored in:
~userdir/vnmrsys/cryo/data/2011-06
The file name is the year and month of the file data.
Filenames start with the date VnmrJ was started.
Error messages are logged in the VnmrJ Error Log.
