Normally we do not use data at wind directions of +/- 45 degrees from 180 (in sonic coordinates). For , in order to eliminate winds blowing through the tower and into the back of the sonic. However, because of the topography at RIM, I used data at +/- 120 degrees.60 about the nominal axis of the gap, SSW or 202.5 deg. The tilt plots are done with respect to the sonic u axis, which was pointed to 253 degrees. Thus in instrument coordinates, the acceptable data is from -10 deg to 110 deg.
Also at RIM, there is a systematic descent of air into the crater, i.e. a vertical flow normal to the "surface". I find more believable realistic lean angles by setting w.off = 0. Used and use the latter results in the RIM cal_files.
Can recalculate these at end of project.
