I tested analysiscut2 on the first 10 days of March 2004.
Some of the showers classified as CHICOS look like they should be
Chiquita. (Chicos showers are marked with an asterisk.)
March 1, 2004
- Shower 17:02:02 -> Junk. Did not show up on old list (newshowers.html),
probably because Chao's filter found a higher Trms.
- Shower 22:47:31 -> Real shower.
March 2, 2004
- Shower 00:48:09 -> Chiquita shower with Caltech 03/1001/3001 triggers.
- Shower 01:18:38 -> Chiquita shower with Caltech 03/1001 triggers.
- Shower 13:34:17 -> Chiquita shower with Caltech 03/1001/3001/96 triggers.
- Shower 18:08:24 -> Junk. Not on old list.
March 3, 2004
- Shower 03:28:53 -> Chiquita shower with Caltech 03/1001 triggers.
- Shower 16:29:23 -> Real shower.
- Shower 18:28:39 -> Chiquita shower with Caltech 03/3001 triggers. Not on old list.
- Shower 18:28:57 -> Chiquita shower with Caltech 03/1001 triggers.
- Shower 23:46:12 -> Chiquita shower with Caltech 03/1001 triggers. Not on old list.

It appears that what the misclassified showers have in common is that they have both a Caltech 03 trigger and a Chiquita trigger. Thus they are being tested as a Chicos shower because of the Caltech 03 trigger, and probably passing the nearest-neighbor cut using the Chiquita trigger. This could happen if the nearest-neighbors to Chiquita sites are not being reset in SetupNearestNeighborsNoChiquita().
Fixed this by re-initializing the nearest neighbors of CIT sites each
time SetupNearestNeighborsNoChiquita() is called. Results:
March 2, 2004
- The two showers that had Caltech 03 and CIT triggers (00:48:09 and
01:18:38) are now correctly classified as Chiquita.
- The one shower that had Caltech 03 and Poly triggers (13:34:17) is still
a Chicos shower, as Poly has 3/5 nearest neighbors hit, even without
Chiquita. This shower could be either Chicos or Chiquita, and probably
should appear on both lists. (Was previously listed as a Chiquita shower.)
March 3, 2004
- Only shower that is still listed as Chicos is 16:29:23.
- The shower at 23:46:12 is gone completely, as it does not pass as a Chiquita shower.
