50000th BeSS spectrum

 I just reached my 50000th spectrum/order submitted in BeSS Be Star Spectra database. The 50000th is a spectrum of EW Lac, and actually a nice one with a Signal-to-Noise ratio SNR~114.


BeSS stats (first in number of Halpha spectra, then all spectra/orders):


About two thirds of thse 50000 spectra/orders have been taken with a semi-auto script in PRISM software.


Note that there is a discrepancy between the BeSS statistics and when I do a search for spectra with Halpha in BeSS - I'm not sure why.


Details of the observatory statistics:

The observatory after last night and having taken my 50000th spectrum !
