how to better identify lines - include upper and lower index in line label
One of the groups at the Warsaw workshop was doing molecules in planetary nebulae. They were very interested in OH and wanted to use a pair of lines that have some diagnostic value and which they had observed. Using the 2010 version of LAMDA these lines are:
46974 OH 17.9807c OH
46979 OH 17.9807c OH
that is - identical wavelengths. They had to give up on using that pair.
They could not even identify the transition within the OH model from the information we provide - the second OH is the line label.
It would help if the label included the upper and lower transition index in the stack of energy levels. The first integer is the index of the line in the line stack - which is another way to get to a line.
This problem is one we shall face more and more as we include ever larger line databases.
