Note (1): Note that for rim E the ^12^CO 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 ^12^CO and/or ^13^CO (classified from 2 to 9, with 2 almost
gaussian and 9 highly departing form gaussian).
