4. http://www.adass.org/adass/proceedings/adass03/reprints/P1-29.pdf
... The results are used in quasireal time by the observing process, but also as input by hardware quality control, by the dynamical scheduler, and by the Science Pipeline. Among processing operations are the calibration of the atmospheric absorption, of phase radiometric correction, of pointing scans, of phase and amplitude reference measurements, .. ... Using the last few measurements, we will determine a provisional amplitude calibration curve (to be also used by the Quick Look pipeline). ...

7. Documentation: LEDA: parameter: vopt
The vopt parameter is computed from the optical measurements in the compilation of redshifts by rejecting outliers and measurements marked for their bad quality and computing a weighted average of the remaining measurements. ... The optical measurements are first selected and converted to a uniform system as: vop = cz + zeropoint(iref) , where cz is the compiled value and zeropoint(iref) a zero-point correction for the reference iref . ... Finally, the individual corrected measurements are combined. ...
