Sažetak
Numerical data reduction of full-disc solar measurements taken in the microwave part of the spectrum (37 GHz) at the Metsahovi Radio Research Station is described. Regions on the Sun with a lower brightness temperature than the quiet Sun level are called Low Temperature Regions (LTRs), and here mainly LTRs are considered. The data reduction includes: to obtain a circular solar picture, to construct twelve radial vectors from the preliminary solar disk center in order to determine the coordinates of the solar limb, to remove "erroneous" limb points, to determine a circle through the limb points by the least-squares method, to obtain corrected coordinates of the solar disk center and the radius and to repeat the procedures using the obtained results as input parameters.
