For historical reasons, it is useful to offer comparisons between the current WFPC2, and its predecessor WF/PC-1, which was returned to Earth in December 1993. Field format: WF/PC-1 contained 8 cameras and CCDs, each CCD having 800 x 800 pixels. ... Many differences derive from the fact that the WF/PC-1 CCDs were thinned, backside illuminated devices whereas the WFPC2 CCDs are thick, frontside illuminated devices. ... WFPC2 devices have much less CTE error, and hence no preflash is used. ...

Both gripes from users and continued spectrum monitoring initiate in-house and off-site searches for the source of Radio Frequency Interference. The digital equipment used in various backends, frequency synthesizers at different mixing stages of the IF/LO, electric motors, video cameras used for safety-status monitoring, on-site vehicles, displays at the Visitor Center could in principle cause internally generated RFI. ...

... Shock is a non-linear plasma wave generated by plasma flow (Burgess, 1995). ... Shocks are thus places where plasma and field go through dramatic changes in density, temperature, field strength, and/or flow speed. If there is no plasma flow through the surface (Un <> 0) or there is no dissipation and compression across it, we talk about discontinuity only, not shock. ... Contact discontinuity . ... Plasma pressure and field strength increase at shock; magnetic field bends away from normal . ...
