2019-09-24	update breakdown cut to include a cut on the number of calibrated PMT hits	tlatorre
	This commit updates the breakdown cut to flag any event in which less than 70% of the PMT hits have a good TAC value.
2019-09-23	update the ITC cut to use pt1 time	tlatorre
	This commit updates the ITC cut to use the pt1 time which is the ECA + PCA without charge walk calibration time. The reason is that an event which is mostly electronics noise may have all low charges which can't be calibrated with the PCA walk calibration.
2019-09-10	add best_uncal_q to the pmt_hit struct and use it in the muon cut	tlatorre
	This commit adds a field to the pmt_hit struct called best_uncal_q which represents the best ECA calibrated charge (in units of QHS counts above pedestals). This is then used in the muon data cleaning cut.
2019-09-09	fix typo in is_slot_early	tlatorre

2019-09-09	update muon cut	tlatorre
	This commit updates the muon cut to require at least 1 OWL hit which has a high charge and is early relative to nearby normal PMTs. This replaces the previous cut criteria which required 2 OWL hits to be early relative to the 10% percentile of all the normal PMT hits. This new cut should target external muons better although I still need to do some testing. In the future I'd like to optimize the distance at which PMTs are considered nearby. Currently I just use 3 meters which seemed like a good value based on some initial testing.
2019-09-09	fix a gcc warning	tlatorre

2019-09-09	update is_slot_early() to hopefully catch more flashers	tlatorre
	This commit updates is_slot_early() to do the following: - use median time when checking to see if the time of the PMT hits in the slot is early relative to nearby PMTs - return True if the number of nearby PMTs is less than or equal to the number of hit PMTs in the potential flasher slot - skip potential cross talk hits when finding the nearby hit PMTs by skipping hits in the adjacent slots with the same paddle card as the potential flasher
2019-09-09	add a first draft of a data cleaning cut to detect breakdown events	tlatorre

2019-09-09	use EHS instead of QHS in is_muon()	tlatorre
	This commit updates is_muon() to use the EHS charge for the OWL tubes since based on looking at the charges for the OWL tubes it looks like the QHS values are completely random.
2019-09-09	lower QLX threshold from 4000 -> 1000 in is_flasher	tlatorre

2019-09-09	switch to using ept instead of pt1 in is_flasher() and is_slot_early()	tlatorre

2019-09-09	only loop over normal PMTs in is_slot_early()	tlatorre

2019-09-09	fix a typo in is_slot_early()	tlatorre

2019-08-27	fix the fts cut	tlatorre
	This commit fixes the FTS cut so that it returns 1 when the event is flagged as failing the cut. Previously, the function returned the following: not enough PMT pairs: 0 (fail) median time > 6.8 ns: 0 (fail) otherwise: 1 (pass) This had two issues: the return value wasn't consistent with the rest of the data cleaning cuts and it should pass if there aren't enough PMT pairs. Now, I fixed the not enough PMT pairs case and made the return value consistent with the rest of the data cleaning cuts: not enough PMT pairs: 0 (pass) median time > 6.8 ns: 1 (fail) otherwise: 0 (pass)
2019-08-27	add the in time channel data cleaning cut from SNO	tlatorre

2019-08-27	update neck cut	tlatorre
	This commit updates the second requirement of the neck event tag to flag events in which either 50% of the normal PMT hits are at the bottom of the detector or 50% of the ECA calibrated charge is at the bottom of the detector. This update was added after testing the cut out on run 10058 which is not in the golden run list and noticing that there were 4 events which were very clearly neck events but which didn't get tagged.
2019-07-16	don't double count PMT pairs in fts cut	tlatorre

2019-07-16	update neck tube cut to include time difference changes due to cable changes	tlatorre

2019-06-23	update how neck events are flagged	tlatorre
	This commit updates the is_neck_event() function to include the requirement that 50% of the normal PMTs in the event must have z <= -425.0.
2019-06-23	update flasher cut	tlatorre
	This commit updates the flasher cut to use the median hit time for all hits in the paddle card instead of just the time of the channel with the highest charge.
2019-06-15	add a bunch more data cleaning cuts from SNO	tlatorre
	This commit adds the following data cleaning cuts: - FTS - OWL trigger - OWL - ESUM
2019-06-14	add a function to compute a data cleaning word	tlatorre
	Also write out the data cleaning word to the YAML file.
2019-06-14	update flasher cut to use pt1 instead of ept	tlatorre
	Small update to the flasher cut to use the non-walk corrected time instead of just the ECA calibrated time. Also added some comments to the variables in the event structure.
2019-06-13	add a data cleaning cut to tag incoming muons	tlatorre
	This commit adds a data cleaning cut to tag incoming muons by looking for early OWL hits. It also significantly updates the flasher cut to catch more flashers. In particular, the flasher cut now does the following: - loops over all paddle cards with at least 4 hits instead of just the paddle cards with the most hits - uses QLX to look for charge outliers in the paddle card - fixes a few bugs (for example, uninitialized values in the charge array) - adds a check to to see if the given slot is early with respect to all PMTs within 4 meters to catch the case where the flashing channel is missing from the event
2019-06-10	add a bunch of SNO data quality cuts	tlatorre
	This commit adds the following data quality cuts used in SNOMAN: - neck - qvnhit - crate isotropy - junk Still need to test these.
2019-03-16	add GPLv3 license	tlatorre

2019-03-04	add a function to tag flasher events	tlatorre
