Hi Michael,
I just finished my thesis revision (I am about to send it to John) and I
will start looking at the last three quantities you asked for
last week (th_e(th_p), phi_e-phi_p, z_e-z_p). I will surely have them
before tomorrow's analysis.

Depending on when the recrunch is ready, I might be able to look at
that too if you send me the location... but it will be very tight (24
hours puts the recrunch time after tomorrow's meeting - in that case I
will do it shortly afterwards).
