Next: The Browne & March? Up: THE DEEP X-RAY RADIO Previous: BL Lacs . Several effects may bias samples of blazars, causing them to miss objects which fall within their survey area and flux limits. ... It is safe to say that there is probably no survey which is completely immune from selection effects. The impact of selection effects upon most previous surveys is not known, but must be understood to make progress towards better understanding the AGN phenomenon. ... The Browne & March? ...

... The well-known spherical aberration in the OTA primary mirror causes most of the light for stellar targets to fall in a large halo (Figs. 2 and 3). The PSF core has nearly the correct diameter, but contains only about 15%of the light. ... The variations with field position are a large effect for WFPC images (Fig. ... This ``breathing'' of the OTA has a noticeable effect on the PSF wings for WFPC data; the wings expand and contract on a timescale comparable to the orbit period. ...

... It should be recalled that most (99.99 percent) of the energy is dissipated by single radiopulsars in the form of relativistic particles and low-frequency electromagnetic waves which are not observable. ... This gives rise to an interesting analog of the classical reflection or heating effect (Lipunov, 1980[ 97 ]; Lipunov and Prokhorov, 1984[ 110 ]; Harding, 1991[ 64 ]; Lipunov and Nazin, 1994[ 119 ]). ...

... arfgen (arfgen-1.75.6) [?? ... arfgen simply constructs the appropriate quantities from the CAL, in the form of vectors of discrete energy-dependent elements, and combines these data multiplicatively to form the ancilliary response. ... This is already taken into account by the CAL in the call to CAL_effectiveArea.
