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 (be sure to use the same units as in the model)
    - <sigma_add>: sigma of the additive gaussian noise (same units as <value>)
    - <mult_noise> (OPTIONAL): multiplicative lognormal noise, provided as an error factor 
                              (e.g. 1.3 means 30% error)
    - <observable display name> (OPTIONAL): alternative shorter names to use on the result figures
