I would be happy to abide by the GalSim naming convention reduced shear :math:`|g| = \frac{a - b}{a + b}` distortion :math:`|e| = \frac{a^2 - b^2}{a^2 + b^2}` conformal shear...

I have started a Membership Policy Draft (visible for Members* to comment on) here: https://docs.google.com/document/d/1vAkBbk1qMRNm4avxFzuCoJd1GKIcwOjXIVSt5erdhX8/edit# *wait, is this definition circular?

@rrjbca hmm... I'm not sure I agree. HI would be an observable which is fundamentally and conceptually different to the other types of observables we have (galaxies, gravy waves etc)...

@Lucia-Fonseca they are fixes to failing codestyle tests which had appeared because (I think) a newer version of flake8 being more strict about whitespace next to keywords like `assert`. They...

@Lucia-Fonseca see #572 :-)

Here are the two rtol plots for CAMB and CLASS for both the massless and massive (m_nu=[0.0, 0.0, 0.06]) cases.  

The above screenshot is a footnote in https://arxiv.org/abs/1403.1873

> @itrharrison the hierarchy you proposed makes sense to me. Should we start a google doc for all members to develop this together, similar to how we worked on the...

Hi @Fox-Davidson, thanks for this PR! Am I right in saying this could also be fixed by making your units for phi* have a h_0 in them? I think doing...
