Setting amp = 0.0 and amp_fixed = True for S07_att (the last row in scipack_ExGal_SpitzerIRSSLLL.ipac) results in the output

"The cosine of the angle between func(x) and any column of the Jacobian is at most 0.000000 in absolute value"

@BethanyRS @karllark I got the same issue when I used run_pahfit. How can I solve it? Thanks a lot.

Simple fix. PR opened (see above). Should be merged soon.
