ACIS SOT Shift Report February 5, 2024

ACIS Personnel: Paul Plucinsky, Catherine Grant

PLAN
----
Run CAP1733 to start a 24 hour ECS measurement after a NSM. The ObsID for this measurement is 62619.  This is a 3-CCD ECS measurement.


CLD File executed:

1A_ECS3B_24H_135.CLD

SUMMARY:
--------

OC/CC were able to come up early on the spacecraft as we were still finishing the CAP review.  The ACA team did two full field searches to improve our knowledge of where the spacecraft is pointing.  After that, we were able to execute CAP1733 to start the ECS measurement. The CAP executed as expected and ACIS is collecting ECS data with S3, I2, & I3.


TIMELINE (GMT day 036)
----------------------

20:10? AOS, came up early on the spacecraft
20:11  OC/CC perform state of health and start SSR dump
20:15  ACIS FSW version 60, science idle, FP Temp = -107.6C
20:25  ACA team conducts full field search
20:30  only 2 stars found, decide to search with a different set of parameters to
       hopefully find fainter stars
20:35  second full field search finds more stars and provides a more accurate attitude
       solution
20:40  start CAP 1733
20:41  enable SCS 107
20:42  ObsID set to 62619
20:44  SCS-135 enabled and activated
20:45  command echoes for WSPOW commands
20:46  startScience command
20:47  FP temp = -107.1 C, 1DPAMZT = +32.2C ; 1DEAMZT = +28.0 C
20:55  1DPICACU = 1.18A ; 1DPICBCU = 0.62A
21:02  Event data telemetering, threshold crossings, event rates , delta overclock look
       nominal
21.05  inform OC that the science run is nominal and we can exit the CAP for now
21:11  FP temp = -106.9 C
21:12  S3 5970 accepted events in 167 exposures, 11.1 cts/s
21:12  I2 5596 accepted events in 167 exposures, 10.5 cts/s
21:12  I3 5454 accepted events in 167 exposures, 10.2 cts/s
21:15  LOS
