... What work is currently being done to improve the flux calibration accuracy for echelle modes? ... Starting early in Cycle 11, monthly offsetting for echelle modes was turned off to minimize these types of calibration problems. ... We are currently working on redetermining the echelle flux calibration so that it is self-consistent with the 2-D scattered light algorithm. Time dependence of the sensitivity - Sensitivity-monitor data for the echelle modes are currently under investigation. ...

... Complex astrophysical phenomena could now be studied spectroscopically: the X-ray absorption line forest intrinsic to Seyfert galaxies; the interaction between AGN jets and intracluster media; hot winds of starburst galaxies; stellar coronal plasmas; the charge -exchange emission of Mars' exosphere; the X-ray irradiation of protoplanetary disks; and the myst erious flat-topped spectral line shapes of O star winds. ... We estimate that Gen-X will be able to detect and resolve 20, 000 stars in NGC...
ST-ECF Instrument Science Report WFC3-2008-16 The TV3 ground calibrations of the WFC3 NIR grisms H. Kuntschner, H. Bushouse, J. R. Walsh, M. KЭmmel July 10, 2008 ABS TRACT Based on thermal vacuum tests (TV3; March/April 2008), the performance of the WFC3 near-IR G102 and G141 grisms together with the new IR detector (IR4; FPA165) has been assessed. ... 6 ST-ECF Instrument Science Report WFC3-2008-16 Figure 2: Instrument efficiency of various orders for the WFC3 G141 grism as function of wavelength. ...

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. ...
