WF/PC-2 9107

The Fundamental Plane for Nuclear Black Holes.

The WF/PC-2 was used to conduct more in-depth searches for
supermassive black holes in galaxy centers. Previous work has led to
the discoveries that {1} most or all hot galaxies contain massive
dark objects at their centers, presumably black holes; {2} there is a
remarkably tight correlation between the black-hole mass and the
luminosity-weighted velocity dispersion of the hot component of the
galaxy. This mbh-Sigma relation has a scatter which is <0.3 dex in
mbh and consistent with zero. This relationship suggests a strong
link between black-hole formation, AGN activity, and galaxy
formation, and once it is understood this link should advance our
understanding of all three processes. The goal of this proposal is to
investigate the scatter in the mbh-Sigma relation and the role of
possible second parameters, by examining a sample of galaxies at
fixed velocity dispersion Sigma=200+/- 20 kms. This approach
decouples the effects of a second parameter from uncertainties in the
shape of the mbh-Sigma relation, and minimizes spurious correlations
because all of the galaxies will be studied using the same
well-tested observational and modeling techniques.

POMS Test Proposal: WFII backup parallel archive proposal

This is a POMS test proposal designed to simulate scientific plans.

WFPC2 9710

POMS Test Proposal: WFII backup parallel archive proposal

This is a POMS test proposal designed to simulate scientific plans.

WFPC2 9676

POMS Test Proposal: WFII parallel archive proposal

This is the generic target version of the WFPC2 Archival Pure
Parallel program. The program will be used to take parallel images of
random areas of the sky, following the recommendations of the 2002
Parallels Working Group. 

WFPC2 9594

WFPC2 CYCLE 11 SUPPLEMENTAL DARKS pt2/3

This dark calibration program obtains 3 dark frames every day to
provide data for monitoring and characterizing the evolution of hot
pixels 

FLIGHT OPERATIONS SUMMARY:

Significant Spacecraft Anomalies: (The following are preliminary
reports of potential non-nominal performance that will be
investigated.) 

HSTAR 8978:  GS Acquisition (3,2,3) {at} 087/16:58:51Z failed to RGA
             control due to SRLE on FGS 2.  Prior FHST updates
             scheduled after the T2 slew showed good attitude
             errors.  FHST Map {at} 087/17:23:11Z Vehicle Axis Errors
             (arcsec) were V1 = -3.652, V2 = 3.105, and V3 = 2.546.
             Subsequent GS Re-acquisitions {at} 087/18:36:23Z and
             20:17:04Z also failed to RGA control.
             The guide star acquisition for this observation was
             non-nominal, further analysis will determine if a repeat
             observation is required.

HSTAR 8979:  GS Acquisition (2,1,2) {at} 089/12:01:25Z resulted in FL
             backup (2,0,2) using FGS 2 during ZOE.  When data was
             received, there were no flags, but FGS 1 had not
             resulted in FL, indicating a FL backup error.  Prior FM
             Updates (U2,3FM) {at} 089/11:45:59Z had a high attitude
             error of -112.376, -12.946, 165.058 arcsec.
             The guide star acquisition for this observation was
             non-nominal, further analysis will determine if a repeat
             observation is required. 

HSTAR 8980:  GS Acquisition (2,1,2) {at} 089/17:03:52Z resulted in FL
             backup (2,0,2) using FGS 2 due to SSLE on FGS 1.  Prior
             FM Update (U2,3RD) {at} 089/16:33:48Z had low attitude
             errors.  Subsequent GS Re-acquisitions {at} 089/18:37:33Z
             and 20:17:33Z resulted in FL backup. Under
             investigation.

SIGNIFICANT EVENTS:

Successfully completed Command Communication Controller (CCC) Test 
087/14:08Z - 14:55Z.
All objectives were met.  Testing was conducted out of the SMOR using
CCC located in the SMOR.  OPS account and OPS profiles were used.

Successfully completed CCS On-Line Data Archive Test on 3/28/03 using
CCS "C" String and SMOR workstations.  Testing was executed in OPS
account to endure required data was available.  Requests for Plots
and Reports were generated with no issues and all objectives were
met.
