Abstract:

The center-limb variation of deltalambda-2, defined as half the distance between the emission peaks in the doubly reversed H- and K- lines was investigated. The observational material consists of spectra obtained at the Solar Observatory, Harestua, during the period February 1, 1964 to January 1, 1966. In undisturbed regions the center-limb variation may be represented by a well defined smooth curve. This is not the case in active regions although there is a tendency for the deltalambda-2 to increase towards the limb. The difference between the measurements in the H- and K- lines is probably due to a systematic error in the observed deltalambda-2 in the H-line. Author
