COS Data Handbook . ... As described in the November 2010 STAN , the gain sag on the COS FUV detector can lead to artifacts in the extracted spectra that look like absorption features. ... Until then we recommend that users carefully inspect their data from the most heavily sagged regions on the detector. ...
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. ...

... 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 . ...

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. ...
