plotting pressure perturbations

[Morgan Silverman]

Heiner,
Thank you for your help. That makes a lot of sense. My question now is
where exactly do I need to do that. I tried just defining them in my
script but it said the variable pertp was not a variable or function name.
That made me wonder if i actually had to go into the subroutines and add
pertp as a variable. Do you know? Thanks
