[yt-users] Field Cuts in Off-Axis Projections

[Munier Azzam Salem]

Hey guys,

       I've been trying to make slices of density only looking at cooler
gas (i.e. with a cut in Temperature). I've found a nice way to do this for
simple projections. But my strategy breaks for Off-Axis projections.

Specifically, this works fine:
*
*
*field_parameters={'field_cuts':["grid['Temperature'] < 1e6 "]})*
*cold_proj =
ProjectionPlot(pf,0,'Density',field_parameters=field_parameters)*
*               *

but this does not:

*cold_proj = OffAxisProjectionPlot(pf,axis,'Density',north_vector=north,*
*                                  field_parameters= field_parameters)*

sensibly enough, since field_parameters is not a keyword argument for off
axis projections.

Is there a decent workaround for this? Or would this be simple to add into
yt's functionality? I've looked briefly into the
source<http://yt-project.org/doc/_modules/yt/visualization/plot_window.html#OffAxisProjectionPlot.__init__>and
it doesn't seem obvious how to slip this in.

      thanks!
            Munier
