EVP Quality Flag Definitions

Quality flag values are assigned by UNH based on a review of the log (TEM) file and DDMCHK plots for each run of EVPRNN. The following quality flag values are presently defined for EVP files:

• <0 = Unacceptable

• null = Not checked by either MPE or UNH

• 50 = Data for which an improved EVP file exists

• 68 = Data generated with EVPTPC to include PSD-II and ToF-VI corrections. Unlike standard EVP data, only completely processed events are included. These data will be superseded by data generated with EVPRNN (v14).

• 100 = Data has passed all MPE operator checks

• 110 = Data processed with old energy calibration (prior to 18-Jul-1991).

• 115 = Cal-3 data processed for IFC.

• 119 = Data with incorrect EHORA which could be improved by reprocessing for the handling of dead PMTs.

• 120 = Data with incorrect EHORA.

• 129 = Data which could be improved by reprocessing for the handling of dead PMTs.

• 130 = Data which has passed all quality checks, with PSD-I and ToF-I corrections.

• 131 = Data which has passed all quality checks, with PSD-I and ToF-II corrections.

• 132 = Data which has passed all quality checks, with PSD-I and ToF-III corrections.

• 133 =

• 134 = Data which has passed all quality checks, with PSD-II and ToF-VI corrections.

• 160 = Approved simulated EVP dataset. Generated by task SIMFIN. Not relevant to flight data.

• 200 = Selected flight data. These data are generated on a per-observation basis. Based on quality 134 data.
