Observational data

In April 1996 the described method was included in the software of automatic data acquisition complex "Continuous". The software was changed after week-long observation at common astrophysical program SAI and SAO. The observer Konnikova V. K. (SAI) observed any discrete sources at West sector of RATAN-600. She was acquired data on the six wide band radiometers of centimeter wavelength. The acquisition frequency was 100 samples per second for each channel with hardware filtering by RC-chain with the value 0.01 sec. At the next step the system made digital integration in real time using data compression with the factor of 10. And the value of the median was calculated as the estimation of medium before change of algorithm. The results of data processing of observations records on the 4--13th of April with respective radiometers are shown in Fig. 4 -- 6. Records of discrete sources (up to 53) were written, and We did not clean records from interferences and sources. More than 400 multifrequency recordings are used in data reduction. Histograms of computed estimates of sensitivities are shown in figures for each wavelength. A shift of histograms picks shows improvement of the real sensitivity of 20--25%. Thit corresponds to the theoretical expectation.

It should be noted that the relatively strong effect of sensitivity improvement for the radiometer of 13cm is due to its engineering tuning and spike depression devices also, which was done in the day of algorithm substitution. This figure shows also that the effect is not visible so obviously at the wavelength of 31 cm, polluted by industrial interferences, apparently caused by low percentage of the general interval of the operation of the linear part of the algorithm.
