@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@ @ @ @ MTA Monitoring Report 6/16/00 - 6/23/00 @ @ @ @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@ Archive of all weekly reports http://asc.harvard.edu/mta/REPORTS/weekly.html Archive of Monthly reports http://asc.harvard.edu/mta/REPORTS/MONTHLY ************ CTI trend ************* Averaged CTI for ACIS-S (without BI) jumped up this week. However, none of individual ACIS-S ccds show the similar jump, so we are investigating a software error. Software Note: Detrended Mn Ka CTI has some problems. Paul Plucinsky (pplucinsky@head-cfa) and Catherine Grant (cgrant@space.mit.edu) pointed out that the drop amp average reported the last week, does not match with their data. Currently, we are investigating where the difference came from. We are currently try to start to apply a linear fit the CTI data with FP temp ~-120C. We don't trust this at all right now but this should be working withing 2 weeks. ************** MTA Problem Tracking ***************** One problem is reopened this week: 2LLDIALV: HRC TRIGGER LEVEL DISCRIMINATOR MONITOR This limit violation was expected. This was due to testing of the HRC associated with exploring methods of operation that would allow the recovery of precise event times. Other problems reported (already open)are: AIOBP5CV, C28VMONB, CUSOB28V, CIUB5V, CIUB5V, CIUB15V AWD1TQI, AWD4TQI, AWD2TQI, AWDTQI, AWD6TQI ******** Trending *********** ACIS Temp 1MAHOAT shows wider scattering than before. Pcad Gyro rate APSIMEC1 usually on sine curve, but often drops to 0.0. Software Note: We are not getting trending data for subbatt, subelec, subeleca, subelecb, teltherm due to mta monitoring does not create following files. /data/mta/www/mp_reports/2000*/subbatt/html/subbatt.html /data/mta/www/mp_reports/2000*/subelec/html/subelec.html /data/mta/www/mp_reports/2000*/subeleca/html/subeleca.html /data/mta/www/mp_reports/2000*/subelecb/html/subelecb.html /data/mta/www/mp_reports/2000*/teltherm/html/teltherm.html The problem will be looked into further. ************* Telemetry *********** No unusal limit violations. *********** ACIS Focal Temperature ******** Acis focal plane temperature peaked three times. Day (DOY) Temp (C) Width (DAY) 167.64 -111.6 0.23 170.28 -111.1 0.23 172.94 -111.3 0.23 *********** Photon Page ************ Manual processing: Acis OBSID DETECTOR GRATING TARGET ANALYSIS --------------------------------------------------------- 103 ACIS-S HETG GX301-2 OK 354 ACIS-S NONE MESSIER 51 OK 15 ACIS-S HETG TZ CRP OK 882 ACIS-I NONE NGC 4395 OK 700 ACIS-S HETG SERPENS X-1 OK 863 ACIS-S HETG ARK 564 OK 240 ACIS-S HETG NGC 1399 OK 374 ACIS-S HETG CIRCINUS GALAXY OK 670 ACIS-I NONE 1912-12 OK 878 ACIS-S NONE PSS 1057+4555 OK 879 ACIS-S NONE PSS1317+3531 OK 1711 ACIS-S LETG 3C273 NO GRATING 1712 ACIS-S HETG 3C273 NO GRATING 1735 HRC-I NONE PSR B0540-69 OK 1736 HRC-I NONE PSR B0540-69 OK 1741 HRC-I NONE PSR B0540-69 OK 62877 ACIS-S HETG CIRCINUS GALAXY OK 1740 ACIS-S NONE (LISTED) 118 ACIS-S NONE 0519-69.0 Pretty 297 HRC-I NONE M31 North 2 OK 285 HRC-I NONE M31 North 1 OK 249 HRC-I NONE M31 South 2 OK 273 HRC-I NONE M31 Center OK 261 HRC-I NONE M31 South 1 OK New CTI OBSIDS 62022 62021 62020, 62019, Following OBSID do not have full analysis: Gratings from AP OBSID DETECTOR GRATING TARGET ANALYSIS --------------------------------------------------------- 103 ACIS-S HETG GX301-2 MISSING ANALYSIS 15 ACIS-S HETG TZ CRP MISSING ANALYSIS 863 ACIS-S HETG ARK 564 OK 374 AICS-S HETG CIRCINUS GALAXY OK 62877 ACIS-S HETG CIRCINUS GALAXY OK 49898 ACIS-S HETG NGC 1399 OK(faint) ACE FLARE 2 hour alert triggered 20000623 ~1200 GMT.
