Hi folks, I received this (rather vague) question this morning and thought I would forward it along to the list for discussion. A couple of FAQ entries seem relevant: http://cars9.uchicago.edu/cgi-bin/ifeffit/faqwiz?req=all#5.6 and http://cars9.uchicago.edu/cgi-bin/ifeffit/faqwiz?req=all#5.7 Perhaps someone could write a FAQ entry on the topic of data alignment...
