New issue 1260: make spectrum with "use_peculiar_velocity = False" https://bitbucket.org/yt_analysis/yt/issues/1260/make-spectrum-with-use_pecu... Pengfei Chen: Hi all, I was trying to make a light ray with "use_peculiar_velocity=False", then trying to make a spectrum also with "use_peculiar_velocity=False", but I got an error. The code I use is here: http://paste.yt-project.org/show/6763/ I should set "field = 'H_number_density'" but since there's no such field in that dataset, I choose "field = 'density'" just to trigger the error. The error message is here: http://paste.yt-project.org/show/6764/ Thanks for your attention, Pengfei
