Fig 2 of SEB paper for two cases Shen08 and Shen10:

here is the Fig 2 using Shen 2008 (Just redoing the Fig 2 in SEB paper for reference)

and then using Shen 2010 and exactly the same format as Fig 2:

well the SEB is NOT completely gone (the orientation of the distribution has not changed) but since Lbol Shen 2010 is scattered with respect to Shen 2008 so the M-L plane-scatter is larger this time.

There are little more objects here in this sample too, since they are not yet crosslisted with R&H sample but that doesn't change anything significantly.

Using sigma_line creates a counter-clockwise rotation with respect to Fig 2(new/old) which looks different in nature.
