Hi Patrick,

I have done a quick test with the pre-983 temperature Jacobian and it now looks 
the same.

Cheers,

Stuart

Subject: Re: [arts-dev] Change to temperature Jacobians

Hi Stuart,

Richard and I have now worked on iyEmissionStandard, and the temperature 
Jacobian produced by this method now considers if effects due to hydrostatic 
equilibrium shall be added or not. We have compared to perturbation 
calculations (though so far only for stokes_dim=1) and all look OK. But we have 
not compared to pre version 983.

Your control file should now hopefully work. If not, tell us. If you compare to 
pre-983, please inform us about the outcome.

Sorry for this mishap in the development. I have now created a test that will 
catch this in the future. And I will try to add even more tests.

Bye,

Patrick
