Skymap launch trajectory plots

Does anyone have time/lat/long/altitude information for the April 1st
Pegasus/TRACE launch, besides the drop point and the injection point
recently posted by Keith Stein?   That sort of information is useful
to plot the launch trajectory.

Recently I used Skymap's launch trajectory plot feature to reproduce
what I hope is a fairly accurate representation of the recent Iridium
launch from Vandenberg.  Using various sources on the web, and a few
guesses on my part, here's the trajectory file I came up with:

  0 34.61  -120.62   0.0
 10 34.60  -120.627  2.5
 86 34.48  -120.66  27.8
131 34.30  -120.70  57.4
274 33.00  -120.80 133.3

For those unfamiliar with Skymap trajectory files, the columns
describe the elapsed time (seconds), lat., long., and altitude (km).
I put some Skymap screenshots of the launch trajectory, as seen from
various locations, at this url:

I'd be interested in hearing from those who witnessed the launch to
find out if the plots are reasonably close to what was seen.
