pyarts.internals.ARTSCAT5(init_data=None)[source]¶ Class to contain ARTSCAT entries that can be accessed and manipulated
Access this data as (N, I, F0, S0, T0, E0, A, GL, GU, PB, QN, LM) = ARTSCAT5[line_nr], where N is the name of the species, I is the AFGL isotopological code, F0 is the central frequency, S0 is the line strength at temperature T0, E0 is the lower energy state, A is the einstein coefficient, GL is the lower population constant, GU is the upper population constant, PB is a dictionary of the pressurebroadening scheme, QN is a QuantumNumberRecord, and LM is a line-mixing dictionary. The dictionaries have keys corresponding to the ARTSCAT tags. line_nr is an index absolutely less than len(self)
Note: Must be ARTSCAT5 line type or this will leave the class data in disarray.
Future tech debt 1: The reading of tagged data will fail if major tags ever match minor tags (ex. PB is major, N2 is minor for PB, if LM ever gets the PB minor tag, then the method below will fail).
Future tech debt 2: To add version number and make the class general, ARTSCAT3 only have minor tag N2 for line mixing and ARTSCAT4 has AP. These tags are however implicit and not written. A
