Comment (by Roland Haas):
I re-ran the example using current master code and got this graph for the error (terr value, plotted as line number vs. column 2):
[[Image(err.png)]]
However looking at the values of the coefficient (or the solution in psi for that matter) reveals that not all is well:
[[Image(ct_testc0.jpg, 600px)]]
namely of the 5 Gaussian blobs mentioned in the parfile only 2 show up.
Some digging reveals that this is b/c of a not-backwards compatible change to CT_Analytic in [https://bitbucket.org/eloisa/ctthorns/commits/d07b160 d07b160] - (tag: ET_2015_11_v0) Reduced number of terms of gaussian[] superposition in Analytic.m in the first version of the thorn in the toolkit.
This is in principle ok since it never supported more than 2 Gaussian blobs while in the ET but we likely should
1. remove the non-functional parameters from param.ccl 1. regenerate the gallery example with the correct data
