Dear Serena,
please find the results below. For comparison, I show the snminuit runs
for Robs' template, new "precise" Peter template (supplied by Rollin),
and the one supplied by you.
Cases are:
1R - HST only, Rob's template
1P - HST only, Peter's template
1S - HST only, Serena's template
2R - HST and discovery point, Rob's template
2P - HST and discovery point, Peter's template
2S - HST and discovery point, Serena's template
3R - HST and discovery point, tmax fixed to Tonry's, Rob's template
3P - HST and discovery point, tmax fixed to Tonry's, Peter's template
3S - HST and discovery point, tmax fixed to Tonry's, Serena's template

(case 3S) http://www-physics.lbl.gov/~fadeyev/snminuit_sn1999q_HSTdisc_fixtmax_uberSerena.ps
I should note that cases 1P and 1S took a lot of time to converge.
Cases 3R,3P,3S have fairly large Chi^2 due to the late-time behaviour
being somewhat incompatible with the assumed tmax from Tonry.
