... For reliable estimation of the accuracy of asteroid CCD observations we usually consider from ten or more various NUMBERED MINOR PLANETS (NMPs) observed during several nigths per month (more then 50 positions). ... They can be considered as an indicator of accuracy of the CCD positional observations with given MPC code. ... For any NUMBERED minor planet the (O-C) values must be zero if the errors of observations and the errors of its theory are absent. ...

... We examine the effects of amplifiers gain fluctuations, of fluctuations in the amplifiers noise temperatures, in the reference load tem perature and in the DC gain ratio. We find that 1=f gain fluctuations are suppressed by proper gain modulation, leaving fluctuations in the amplifiers noise temperatures as the main source of 1=f type noise. ... 4 Discussion and conclusions We have shown that the dominant source of 1=f noise in the radiometer output is amplifier noise temperature fluctuations. ...
