Well no that fix should go directly into the Rocker definition so that it's always correct by default.

Forcing the Ricker source to be zero-mean will lead to resampling failures. I guess we can make zero_mean an option and make it false for the resampling test. Please advise. Thanks!

[mloubout]

What do you mean resampling failures ?

[ziyiyin97]

The test_resample.py failed

[mloubout]

Right because the mean correction gonna be slightly different. I would probably just patc the test adding some tolerance rather than adding an extra argument

[ziyiyin97]

Yes I raised the tolerance of the resampling test.
