Sheila found two issues when modifying the H1ASC.txt filter file this morning:

 1. A change to an existing filer caused foton to freeze up

 2. Loading a change to a filter (which was turned off) onto h1asc caused lock loss

I suspect both issues were due to the fact that today was the first time the h1asc filterfile was being handled by the new version of foton (with the higher number of significant digits in the gain).

issue 1) We later found that the foton freeze up could not be reproduced, perhaps it was because the old format file was being read and modified? We'll see if this error appears in other systems.

issue 2) Since every gain was recalculated with the higher number of digits, perhaps loading all the filters glitched the system enough to cause lock loss? One suggestion is that if a filter file is being changed to the new format for the first time, we should only load all of  the filters on a Tuesday morning (or perhaps perform this full load on every model at that time).
