Input measured values below

Input must be ratios to H alpha. Halpha must stay as 1, though its variance won't affect the results. It is important that the same "Line" names be kept because they are used within the program both to match lines to the database and to calculate reddening. The data must be tab separated. The easiest way to manipulate it is probably using Excel: copying and pasting from Excel will give you tab separated values. The lines listed below are those currently in the database, others can be added if necessary.



Line Ratio to HA Var

Input C, the logarithmic extinction of H-Beta, here. It will apply the reddening correction using Cardelli, Clayton, Mathis (1989)'s formula and modify the values you put in the above table
