The Analyses of the Accuracy of Solar Radio Observations at Yunnan Observatory During the Peak Years of Cycle 21

In this paper we use the folding-regression analysis, to make the analyses respectively between the solar radio observations at 9375 MHz, 3653 MHz and 2902 MHz at Yunnan Observatory and those of 9400 MHz (Toyokawa), 3750 MHz (Toyokawa) and 2800 MHz (Ottawa). In the period of Jan. 1980-Dec. 1982 the results show that the r. m. s. errors of the total flux density are and 5.6% respectively. For the bunt observation in the same period, we replace the 2800 MHz (Ottawa) by 2695 MHz (Manila) but still keep the Toyokawa's, results show that the r. m. s. errors of the peak flux density of solar radio burst are 13%, 24% and 20% respectively.
