Could it be a blend?

The residuals plot after the (presumably) Gaussian profile has been subtracted appears asymmetrical to me, with the left hump being somewhat larger than the right.

https://arxiv.org/abs/1809.00018 came to my attention a few days ago which is what made me think of this possible explanation.
