aer_opt

Hello,
  I just want to confirm that even when I use aer_opt=-99, Rhos will include correction for gases. Or do I have to specify this?
Thanks much.

Hello Sean,
  Thanks so much for the explanation.  Is my understanding correct that no matter what aer_opt I use (or use -99 for no correction) Rhos values will not be affected by it?
Thanks again for your help.
