Data can be aquired through IDL with the function savephotons
result=0 (if no data was saved)
result=1 (if data was saved)
"savephotons" will request data from the Linux-computer called rphot.
The data file will be a text file with a single column of
integers. The number
of integers will equal nsamples. Each integer represents the
total photons counted during a period of (1/rate).
0 < nsamp < 5e5
0 < rate < 5000 Hz (the rates
must be chosen such that (10000/n), n is an integer greater than
0 <= counts < 65535
ISSUE (error making connection):
If result=savephotons=0 and there is a message "error making
rphot doesn't have it's server running.
To start the server on rphot: (1)"ssh firstname.lastname@example.org",
