Variance in origin sources spectra issue
Using mpdaf latest version (1.3.dev) on my computer, it seems that I can't access the variances of the sources sprectra using the mpdaf tools. But, I can access them with astropy and on the urania4 server that problem doesn't occur. I use Numpy 1.11.0, Astropy 0.4.2 and Python 2.7.11 |Anaconda 2.1.0 (x86_64)|. The files concerned are on urania4 : /home/desprezg/Origin/orig-udf10/
