Transitions in BP's line list

Lambda doubling

-- BertrandPlez 28 Jan 2009:

Some transitions are affected by Lambda-doubling. In that case there are 2 sublevels that give rise to transitions, and if the separation is large enough, they appear in the list as 2 lines with the same parameters except for the parity of the upper and lower level, and a slightly different wavenumber. The degeneracy of these sublevels is 2*J+1. When the Lambda-doubling is too small there are 2 lines with exactly the same data (except the parities). One way to compact the list is to merge these lines and double the gf-value 2*(2*J+1)*f.

For some transitions Lambda-doubling does not exist (if Lambda=0, i.e if one of the states is a sigma state).

Observed wavenumbers

A separate list with observed wavenumbers from Phillips (Bertrand Plez, priv. comm. 17 Sep 2008) and calculated other values from Plez, will be generated. Reference: Davis et al. 1986, ApJ 309, 449.

The original list is at /h19/ulrike/Molecules/Data/TiO/TiO-Phillips-OBS.dat

It contains alpha, beta, gamma, gammaprime transitions (systems) with range:

wavenumber(cm^-1)	wavelength(Å)
20997.630	4762.4422
14729.730	6788.9907

Isotope: ⁴⁸Ti (see Davis et al. 1986, IV.a p. 452)

Content: "Obs", vupp, vlow, Jlow, "+", branch, ".0000E+00", wavenumber, ".000", system

There are a few "double" lines with same quantum numbers and branch names (but different wavenumbers). The wavenumbers for these will be averaged.

beta system:

v-v	branch	J_low range	J_low missing

0-0	P	4<=Jlow<= 99	94
