New issue 605: PlanckTransferFunction does not support grey_opacity https://bitbucket.org/yt_analysis/yt/issue/605/plancktransferfunction-does-n...
From wlad on IRC:
line 611, in finalize_image
if self.transfer_function.grey_opacity is False: AttributeError: 'PlanckTransferFunction' object has no attribute 'grey_opacity'
@jwise77, @samskillman do you have any thoughts about this? I've never used the PlanckTransferFunction but that's mostly because it's not documented very well. If we could shore it up I think it would be a very useful thing to have around.
