... We have measured this "redshift" for the pink black holes, and allowed for it in our calculations. ... We see this effect in the emission from gas around these pink black holes, but it is far too small an effect to account for the pinkness. Thus the swirling motions of gas around or into the black holes cannot produc the colour. ... At first we thought that these things were normal blue black holes hidden behind clouds of interstellar dust, that absorbed the blue light and made them appear pink. ...

Technical Instrument Report WFPC2-97-08 SMOV Flat Field Check (prop-ID 7019) J. Biretta and M. Wiggs January 20, 1998 ABSTRACT We compare WFPC2 Earthflats taken before and the field-of-view shows no change (<<1%) in flat and occur within a few pixels of the CCD corners utable to long-term changes in the camera / OTA after the 1997 service mission. ... We then divided the SMOV flat by the pre-SMOV image, and normalized so that the center 400 x 400 pixels of WF3 had a mean of unity. ...

... Watchouts . ... It associates incorrect energies with line features below 1 keV by shifting them to lower energies and applying too much redistribution. Fig.1 compares the SASv6.0 result (red curve) with the SASv5.4 result (black curve) for a 0.8 keV line feature. ... Currently SAS 6.0 leads to obviously very bad fits at low energies, while the MOS-timing canned-response produces fits in excellent agreement with MOS small-window mode down to 100 eV (as shown in Fig.2). ...
