[yt-users] 1D matter power spectrum

[gso at physics.ucsd.edu]

Got the following error at the bottom of this email.  I'm using the
Metadata-Version: 1.0
Name: yt
Version: 2.1dev
according to dev-yt/src/yt-hg/yt.egg-info/PKG-INFO
it's the version installed with the install script, do I have to do
something else to change branch? like >hg up -C yt
or something else?

From
G.S.

> phi : Float
>     Similar to theta above, but the range of values is [-pi/2, pi/2].
