... Assured of a reliable method of solving the normal equations, we now consider the equations of condition. The observed magnitude m of a star at M air masses with true instrumental magnitude is modelled as ([ 10 ], [ 28 ]) . ... The effective extinction coefficient depends on the effective spectral gradient [ 29 ] of the star, for which we use some color index, affected by half the atmospheric reddening ([ 26 ], [ 10 ]): . ... Thus, for the B band of UBV, we use the (U-V) color. ...

The overall efficiency (including atmospheric transmission, reflectivity of the telescope mirrors and overall efficiency of the optics and of the detector) for broad-band imaging should be about 25% in H and K, and about 15% in J. The main noise source for both broad- and narrow-band imaging should be the photon noise associated to the background+source flux. ... Flat fielding (and possibly background subtraction) might increase the noise by a factor 2 ? ...

... Less than 1% of 20cm observing time would be lost to bad weather. ... Over the winters of 2002-2004, the so-called "swap" scheme has been used to give 3mm observers some robustness to poor weather. With this scheme, a pair of 3mm and centimetre proposals are partnered and scheduled typically a few days apart. At the discretion of the 3mm observer, the order of the 3mm and centimetre proposal can be swapped to give the 3mm observer the best chance at good weather. ...

... Also the measured signals are affected by detector transients, altering the final results considerably. We present the design and the main features of a software package, developed in order to support the absolute calibration of the instrument. ... In case the fit is not successful, the average of the last 30% of the data is taken as the final signal. ... The two different symbols represent individual calibrations of the final background signals, using the first or the second FCS-signal. ...
