I have been using the wrf_cape_3d routine with output from several models and have seen the resulting CAPE of -0.1. I had assumed that the function returns -0.1 instead of 0. Am I correct with my interpretation, or is an "out of bound"-value related to the error message: "capecalc3d: Outside of lookup table bounds", or is it something else entirely?

Further, I am confident that I use the correct units for my input variables (in particular Pa for the "p" variable and hPa for the "psfc" variable).

I have searched the archive for the latter, but haven't found a useful entry. Also, would you know the bounds of the lookup table, so that I could check my input?
