Technical Instrument Report WFPC2-97-07 WFPC2 internal monitoring for SM97 (Program 7022) Max Mutchler and Massimo Stiavelli August 28, 1997 ABSTRACT The goal of SMOV proposal 7022 was to verify that there was no change in basic WFPC2 instrument health and internal calibrations. ... Summary In general, analysis of the data from program 7022 shows that the 2nd Hubble Space Telescope servicing mission of February 1997 caused no significant changes to the basic health and internal calibration of WFPC2. ...

... The science from both these missions contributed to three of the Nobel Prizes Giacconi (2002), Mather, and Smoot (2006) - awarded for NASA-based science. ... We encourage NASA to seek new launch capabilities to fill this strategic gap in moderate lift rockets to enable the Explorer program to continue launching missions with significant science payoff but reduced costs and timescales compared to large strategic missions. ... 18 Appendix B: Explorer Missions 1989-present (From PILMSS) No . ...
ST-ECF Instrument Science Report ACS-2008-01 Updated flux calibration and fringe modelling for the ACS/WFC G800L grism H. Kuntschner, M. KЭmmel, J. R. Walsh January 25, 2008 ABS TRACT A revised flux calibration is presented for the G800L grism with the ACS Wide Field Channel. ... We also include in this report an extensive investigation into the potential effects of fringing on the flux calibration based on the WFC CCDs fringing model as described in ST-ECF ISR ACS 2003-03 (Walsh et al. ...

CORES OR CUSPS IN ELLIPTICAL GALAXIES: LUMINOSITY OR ENVIRONMENT? ... The low lumi nosity disky galaxies have `hard' cores with a steep slope in the luminosity profile at small radii, whereas the luminous galaxies have `soft' cores with flat profiles at small radii (e.g. Faber et al. ... Coma Cluster cores In the gas/stellar continuum paradigm, one would expect that in the outer parts of a cluster it is more likely that the last merger was gaseous than in its central regions. ...
