My first P cyg

Post by Stephane Ubaud »

hello,

I tried my luky with P cyg on monday the last week, with my LHIRES III, i stack 7 exposures each 600s

I mesure EW=-71,4 A ; is that correct? I take the emission line and the absorption part.

hello Stephane
I try on my side also for the first time P cyg. Curve seem very similar to your. Sorry, i do not know how calculate the EW. I suppose this is describe by Ernst on his web site.
30x60sec, C14, LHIRES 2400 line/mm, slit 35 micron. Resolution calculate by ISIS is R= 11000.
Spectra available here: http://perso.crans.org/~lemoult/spectro ... 4_882.fits
