I think at that frequency you should be fine with only H2O and O2. If the

Hi Gerrit,
a great initiative!
Comments:
When I tried searching for “arts” on wikipedia, however, it does not show up.
Is there anything special that needs to be done for it to also be searchable by

Dear Pengwang,
are you sure this is a spectral problem? The ARTS LUT does not do any spectral
interpolation, only interpolation in pressure, temperature, and water vapor
concentration. It could be these other interpolations that lead to negative
values, if the real absorption is close to zero.

Ups, sorry! My memory was wrong, I think. But copying in Alex just in case he
has any comments.
Perhaps a stupid question: why do you want to include the antenna in a 1d case?
Do you expect a significant effect towards the edge of the scan?
