With help from TJ, I migrated a majority of the ASC filters controlled by ISC_LOCK into an lscparams dictionary called asc_filters, and edited the filter engagement/disengagement commands in the guardian to call from this dictionary. Along the way, I also edited the lscparams asc_gains dictionary, and removed commented out code that seemed unnecessary or out of date.

New practice: each dictionary entry in asc_filters includes ALL filter bank settings that should be ON at a given time, so all filters to be engaged as well as OUTPUT, DECIMATION (INPUT as well, if it is supposed to be on). When filter changes are made, we can use the command ezca.get_LIGOFilter([DOF]).only_on(*lscparams.asc_filters[DOF][P/Y][NAME]). The names of the filter settings are named after the guardian state in which they are engaged, with some small edits if one guardian state has multiple filter engagement steps.

Example:

In PREP_ASC_FOR_FULL_IFO, CSOFT P filters are set up, but the input is left off until engagement in ENGAGE_SOFT_LOOPS. Then, after the loop is engaged and converged, FM1 is disengaged. Finally, in POWER_25W, FM3 is engaged as a boost.

The dictionary is set up as:

In PREP_ASC:

Therefore, when we make adjustments to ASC filters or gains, we will need to edit the dictionaries in lscparams. This will ensure that any changes also get picked up by the seismic guardian.

These are things that are not yet controlled by this dictionary:

• none of these ASC loops included offsets, so the filter bank settings do not engage the offsets. However, using the "only_on" command can disengage an offset, if it is not put into these settings.
• the ASC BLEND filters for the HARD and SOFT loops are still controlled outside of this dictionary
• I left MICH ASC filtersout of the dictionary for now, since its settings are first controlled by ISC_DRMI and then the loop is left on thereafter.

TJ is currently editing the seismic guardian to create the ASC higain state and then a state that takes ASC back to its lownoise state. Now, we can pull the gain and filters settings from these dictionaries!
