Dear Sir,

Question is about the internal coordinate IC statements in the topology
files. Referring to paragraphs in NAMD Tutorials - Appendix C TOPOLOGY
FILES, where
"Improper IC statements are indicated by a * preceding the third atom, the
atom to which the other three are bonded, as in 1 2 *3 4."

However, there are several lines in the IC section when there is
no asterisk (*), so which would be the third atom for the angles and

Thanks for your time.
