. XMM-Newton Science Analysis System . epchain (epchain-8.60.1) [???] . Meta Index / Home Page / Description . As the final event file does not contain events below 150 eV, the information to assess the presence of optical loading in a straight forward way is not available in the event file anymore. Parameter optloadingimage therefore controls the optional creation of an image in the ADU 20-30 range where optical loading is easily visible. XMM-Newton SOC/SSC -- 2007-11-26

We present a catalogue of galaxies for which spatially resolved data on their internal kinematics have been published; there is no apriori restriction regarding their morphological type. The catalogue lists the references to the articles where the data are published, as well as a coded description of these data: observed emission (E) or absorption (A) data, optical (O) or radio (R) data, velocity (V) or velocity dispersion (D), radial profile (1) or 2D field (2). ...
