Description

We provide mode identifications of all the ~2500 RGB stars and a table that includes all the fitting results.

In the file "mode_ID_for_2500_RGB.zip", you can find a lot of folders with KIC number in their folder names. In each folder, the files "KIC*l*n*fitting_detail.dat" show the Lorentzian profile fitting for l=0 or 2 modes (see l value in the file name). The first row is the fitting result (the frequency value is in the second column) and the second row is uncertainty.

for l=1 mixed modes, you can find them in the files "KIC*bin_points*for_l_1_m*.dat". This is just an approximation of the mode frequencies. You should run a Lorentzian profile fitting using these frequencies as initial guess to obtain a precise mode frequency.
