... In the first page of this chapter, Eddington computes an effective temperature of 3.18 K, but this has nothing to do with the 2.725 K blackbody spectrum of the Cosmic Microwave Background (CMB) . Here is a quote of what Eddington actually said: . ... We shall first calculate the energy density of this radiation. ... It is clear that Eddington's model fits the optical data, but that Eddington did not anticipate either the CMB (red curve) or the interstellar dust (ISD, green curve). ...

... The WFPC2 CCDs have a small b ut significant charge transfer efficiency (CTE) problem which causes some signal to be lost when charge is transferred down the chip during readout. This has the effect of making objects at higher row numbers (more charge transfers) appear fainter than they would if they were at low row numbers. The effect depends on the temperature of the CCDs. ... It is also possible that proportional losses for fainter stars, at least with no background, may be larger. ...

H I Self-Absorption (HISA) arises from cold H I gas in front of warmer H I emission at the same velocity. HISA is thus a unique probe of the velocity and temperature structure of the Galactic ISM, from sub-parsec scales within clouds up to multi-kiloparsec scales across the disk. ... To address this question, a series of simple H I radiative transfer models of the Galaxy will be presented. ...

... The current MOS procedure envisages a less complicated correction mechanism than for the PN. ... The CTI correction applies a scalar correction to the event list set, on an event by event basis, in order to correct for loss of charge which has occurred in reading out the CCD array. ... We expect to correct for a fixed amount of charge loss, and a fractional amount of charge loss, which depends on the number of row and column transfers completed. ... http://xmm.vilspa.esa.es/ xmmdoc/MOS/mos_cti.html ...
