[MSNoise] plotting error

[Thomas Lecocq]

Kasper,

When you changed the mov_stack value, did you re-run MSNoise "from 
scratch". The thing is, if jobs have already been done, say, for January 
1 -> January 10, then you modify the mov_stack, and run s04_stack.py a 
few days after, Jan1->10 will not be stacked for the 30 day mov_stack. 
you have, at least, to run s04stack.py with a "--interval X" (X > 1, 
your case probably 20 or 30 max), so the CC jobs in the last 30 days 
will be re-considered for stacking.

As of the plot problem, I've noticed a slight bug in the get_stations() 
in the database_tools, but that should only affect the results iif the 
stations were input manually in the database and thus not necessarily in 
alphabetical order: 
(bugfix:https://github.com/ROBelgium/MSNoise/commit/0dca3cfe101c56f3ed8f6e53741285709ab58f30). 
In your case, it looks like the 1-day data is not loaded, could you 
confirm the data is present in the folders/files archive ? You could 
also print the "day" variable, to know which file is "empty" and causes 
the bug. Normally, empty dtt files should not exist...

Let me know,

Tom
