✦ Synopsis

The discrepancies in the values of longitudinal magnetic field obtained from magnetographic records in different spectral lines are considered. On the basis of extensive data including 60 pairs of magnetographic maps for 11 spectral lines, obtained simultaneously for one of these lines and 26103 with the aid of the Crimean double channel magnetograph, the following conclusions have been reached. The relative field strength 6(20 = Hil(2i)/Hil (6103) depends partly on the distance from the center of the disk (Figure 4) and mainly on the magnetic sensitivity of the line g22 (Figure 3), pointing to the primary role of saturation effect. The possible influence of line asymmetry on these discrepancies is also suggested.
