Type 1 observational constraint per line.
For example:

"I(CO v=0,J=4->v=0,J=3 angle 00 deg)" 3.5E-06 3.2E-7 "CO (4-3)"
"I(CO v=0,J=5->v=0,J=4 angle 00 deg)" 3.2E-06 1.1E-6 "CO (5-4)"
"I(CO v=0,J=6->v=0,J=5 angle 00 deg)" 1.3E-06 7.3E-7 1.3 "CO (6-5)"

Help

Each observational constraint uses the following format:


    "<observable name>" <value>  <sigma_add> [<mult_noise>] ["<observable display name>"]
    
    - <observable name>: quantity name used by the model (use the search bar above)
    - <value>: observed value, e.g. integrated line intensity (be sure to use the same units as the model)
    - <sigma_add>: sigma of observational uncertainties (additive gaussian part, same units as <value>)
    - <mult_noise> (OPTIONAL): additional multiplicative lognormal noise, provided as an error factor 
                              (e.g. 1.3 means 30% error)
    - <observable display name> (OPTIONAL): shorter alternative quantity names for result graphs
