Note (1): Note that for rim E the 12CO T*R is only assumed
(two times the value found in the fit, indicated by an asterisk) and
that the related values {DELTA}V and R(1) could be doubtful
Note (2): Departures from the gaussian line shape have been detected
for 12CO and/or 13CO (classified from 2 to 9, with 2 almost
gaussian and 9 highly departing form gaussian).

the derived values are based on smaller diameter, i.e. 80% of the
derived diameter in column Diam.
