Solar Limb Effect of the Spectral Lines in a Prominence Observed at the Total Eclipse in 1941

Analysis of measured high-resolution doublet rovibronic spectra and related line lists of 12CH and 16OH

“…Although we aim to process all experimentally measured transitions, sometimes the earlier experimental studies are just too inaccurate to justify their inclusion into the MARVEL input transitions file. For example, in the case of the A 2 S + -X 2 P band, the average uncertainty of the 9200 lines of 18YoBeHoMa 53 is about 5 Â 10 À4 cm À1 , while the accuracy of earlier works, for example, 34TaKo 166 and 62DiCr, 167 is significantly worse, only about 0.01À0.1 cm À1 . Consequently, we decided to exclude these sources from our analysis.…”
