strange spectrum in the literatur
Posted: Fri Dec 07, 2018 4:48 pm
Dear colleagues,
in the literature I found within a certain publication the präsentation of Halpha EW measurements of P Cygni (see attachment). I have strong doubts that the presented Halpha spectrum of 2017-04-30 corresponds the reality. The enormous absorption within the Halpha profile seems to be very unlikely.
Unfortunately there are no spectra in the ARAS data base around that date. Could P Cygni observers to be so friendly to have a look into their own privat data pool in order to find a Halpha spectrum around that date?
Many thanks for your effort,
Ernst Pollmann
