[Ifeffit] sum path NAN?

Bruce,

I use Ifeffit and Horae packages under Debian built by Carlo so launching 
Artemis from the command line:

$artemis&

at each fit, during the minimization process, appear in the standard 
output, that is in the shell where I executed the program many lines (one 
for each path at each minimization step, if I well understand it) that 
have this form:

sum path #1 #2 #3 #4

Where #* are real numbers and sometimes appears "NAN" that, as Matt said, 
seems a division by zero or a log(-1). I'm trying to produce a project 
file that will show the case when the minimization fall in all "NAN" and 
the loop need to be killed to stop. I'll post it as soon as possible, but 
in the meantime is useful to understand these numbers that appear in the 
shell.

M.
