I have been away for several weeks and will try to sort this out soon. dana ----- Original Message ----- From: "Bjorn H Samset" <bjornhs@rcf2.rhic.bnl.gov> To: "BRAHMS main list" <brahms-l@bnl.gov> Sent: Wednesday, October 15, 2003 9:59 AM Subject: Correction functions for TD1 and TMrsF > > Hi all. > > Some time back Eun-Joo made some decay/multiple scattering/absorption > corrections that have been really useful in our analyses.
