The goal of this report is to provide a means for communicating those EVP runs which were rejected or have not yet appeared at UNH. It will provide information as to why a run is rejected. A summary of the DRG-accepted EVP datasets is available from the database by query on the quality and TJD range. DOCUMENT HISTORY ================ 03-Dec-92 Issue 1 First issue.

This includes data from TJD 8717 up through TJD 8956. Starting with TJD 8957 (1-Dec-92, the start of observation period 203.0), all routine processing has been peformed to process those modules with failed PMTs. This means that data between TJD 8717 and TJD 8958 can benefit from reprocessing. In general, we can define five time periods of processing: 1) launch - TJD 8717 (5-Apr-92) : Obs periods 1-24.0 These data were processed with incorrect EHORA information for each event. There are no plans to systematically process these data to correct this problem. These EVP datasets have QF = 120. 2) TJD 8717 (5-Apr-92) - TJD 8818 (15-Jul-92) : Obs periods 24.0-33 These data were processed with incorrect EHORA information for each event. The failure of one or more PMTs for these data suggest that these data will benefit from reprocessing. Those datasets identified for reprocessing are given a QF = 119. Once properly processed, the new EVP dataset has a QF = 130. 3) TJD 8819 (15-Jul-92) - TJD 8956 (30-Nov-92) : Obs Periods 34-202 These data were processed with the correct EHORA information for each event. PMT failures, however, suggest that these data can benefit from reprocessing to handle the failed PMT modules. Those datasets identified for reprocessing are given a QF = 129. Once properly processed, the new EVP dataset has a QF = 130. 4) TJD 8957 (1-Dec-92) - appx TJD 9247 (17-Sep-93) : Obs Periods 203.0 - 302.3. These data have been properly processed, with regards to both the EHORA information and the handling of dead PMTs. 5) appx TJD 9247 (17-Sep-93) - present : Obs period 302.3 - All data processed from 4-Oct-93 onwards incorporates an improved ToF correction. This includes all data from appx TJD 9247, but it also will include any data from earlier in the mission which has been reprocessed after 4-Oct-93. ====================== EVPRNN VERSION HISTORY ====================== This section lists all of the versions of task EVPRNN relevant to flight data processing. EVPRNN 3 Dec 14, 1990 to Feb 2, 1991 some calibration data processed EVP file records 172 bytes each. EVPRNN 4 Feb 2, 1991 to 25 Mar 1991 some calibartion data processed EVP file records 68 bytes each. EVPRNN 5 Mar 25, 1991-May 8, 1991 Some Flight Data EVPRNN 6,7 May 8, 1991-Jun 3 1991 CP EOF recognition correction Check OAD record for 0 as x,z axes RA & DEC is error. EVPRNN 8 June 3, 1991- Dec 16, 1991 REM EOF recognition correction. EVPRNN 9 Dec 16, 1991 - Aug 17, 1992 OAD rec gap max 32 sec at start EVPRNN 10 Aug 17, 1992 - Sep 13 1992 EHA correction. QF set back to 120. EVP datarep 3 in the DSD table. EVPRNN 11 Sep 13, 1992 - Oct 4, 1993 Neural location in double precision Requires new generation NL3 maps both full and missing PMT EVPRNN 12 Oct 4, 1993 - improved TOF correction. Quality 131 introduced. EVP datarep 3 in the DSD table. EVP-DAL routines were also changed at this time so that earlier versions of EVP datasets were modified for the ToF when read within COMPASS. EVPRNN 13 Nov 1994 - present Title appends gamma class from PTT entry ================================== EVP DATASET REPRESENTATION HISTORY ================================== This section lists all of the versions of the EVP dataset representation that exist within COMPASS. 0 - Preflight data, 172 bytes per record. Some calibration data exists in this format. Not used after Feb 1991. 1 - Coincides with the delivery of EVPRNN 4. The first flight data used this format. In effect from Feb 1, 1991 to Aug 17, 1992. This data was compacted to be only 68 bytes per record. It was later found that this data has incorrect EHORA. 2 - Coincides with the delivery of EVPRNN 10, the correction of the EHORA. In effect from 17 Aug 1992 to 5 Oct 1993. This is also 68 bytes per record. 3 - Coincides with EVPRNN 12, which incorporated an improved ToF correction. It has been in effect since Oct 5, 1993. It is also 68 bytes per record. ============================ 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 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, but does not include proper ToF corrections. 131 - Data which has passed all quality checks and which includes improved ToF corrections. No further improvements can be made. 132 - Data which has been generated by IFCTCF to incorporate the best possible TOF corrections. ===================================== HISTORY OF ERRATIC AND/OR FAILED PMTS ===================================== Modules with erratic PMTs cannot be properly handled within the COMPASS processing environment. Once a PMT has completely failed, however, it is possible for COMPASS to process the data for that module. The following PMT failures have now been noted: D2-13, PMT-2 TJD 8717 07:40 UT D2-11, PMT-6 TJD 8736 01:35 UT D2-14, PMT-4 TJD 8755 00:28 UT D2-02, PMT-1 TJD 8988 23:47 UT John Macri has provided the following info on PMT failures. These data provide only a general overview of each case. Further details can be found in CRAPs. D2-01, PMT #1: Problem first noted by ITOG on TJD 9165 (27-Jun-93) at 18:42. HV has been left on. Erratic behavior still observed. D2-01, PMT #2: Problem first noted by ITOG on TJD 9279 (19-Oct-93). HV has been left on. Erratic behavior still observed. D2-01, PMT#4: Problem first noted by ITOG on TJD 9340 (19-Dec-93) at 9:48 UT. HV has been left on. Erratic behavior still observed. D2-01 module has been shut off August 3, 1994, TJD 9567 17:41 UT. D2-02, PMT #1: Problem first noted by ITOG on TJD 8654 (2-Feb-92) at 21:06. HV was left on. Total PMT failure on TJD 8988 (1-Jan-93) at 23:47. D2-11, PMT #6: Problem first noted by ITOG on TJD 8652 (31-Jan-92) at 13:22. HV was turned off from TJD 8655 (3-Feb-92) at 2:37 until TJD 8734 (22-Apr-92) at 17:31. Total PMT failure on TJD 8736 (24-Apr-92) at 1:35. D2-13, PMT #2: Problem first noted by ITOG on TJD 8645 (24-Jan-92). HV was turned off from TJD 8645 (24-Jan-92) at 16:23 until TJD 8658 (6-Feb-92) at 18:56. Total PMT failure on TJD 8717 (5-Apr-92) at 7:40. D2-14, PMT#4: Problem first noted by ITOG on TJD 8398 (22-May-91). HV was turned off from TJD 8401 (25-May-91) at 1:11 until TJD 8755 (13-May-92) at 00:28.
