- sbpy.activity.total_number(mol_data, aper, b)¶
Equation relating number of molecules with column density, the aperture, and geometry given and accounting for photodissociation, derived from data provided. Feel free to use your own total number to calculate production rate or use this function with your own molecular data as long as you are aware of the needed data.
Integrated flux of emission line.
sbpy.data.physobject that contains AT LEAST the following data:
- Transition frequency in MHzEinstein Coefficient (1/s)Beta: (Timescale (in s) * r^2 (in au))Column Density in 1/m^2
The values above can either be given by the user or obtained from the functions
beta_factorKeywords that can be used for these values are found under
fieldnamesdocumentation. We recommend the use of the JPL Molecular Spectral Catalog and the use of
from_jplspecto obtain these values in order to maintain consistency. Yet, if you wish to use your own molecular data, it is possible. Make sure to inform yourself on the values needed for each function, their units, and their interchangeable keywords as part of the Phys data class.
An astropy Quantity containing the total number of molecules within the aperture (Dimensionless)
