• How to get started with the LBL once you have followed all the installation instructions:

In the science/ folder (or wherever your config file points to), you need to have an FP folder and put all your_ C.fits FP e2ds files there. You will also need to put the start/end-of-night calibrations (e.g., 260264F0T1a_pp_e2dsff_C.fits). Once you have extracted all your lblrv files for the FPs, you should see the drift.rdb file in the rdb folder. This is required to get drift-corrected velocities.
