DEBiL Release Notes (ver. 1.1) ================================= Input files: ============ Light curve format (3-column): ------------------------------ Column description: 1. float Time stamp 2. float Magnitude 3. float Magnitude uncertainty (must be positive) Examples: 535.826113 -1.000 -1.000 541.870983 17.009 0.028 550.862006 17.036 0.012 Light curve OGLE-format: ------------------------ Currently we incorporate the OGLE light curve format. Column description: 1. float Time stamp (must be positive) 2. float Difference flux (ignored) 3. float Flux uncertainty (ignored) 4. float I-band magnitude (must be positive) 5. float I-band magnitude uncertainty (must be positive) 6. int Flags (ignored) Examples: 535.826113 -99.00 -99.00 -1.000 -1.000 6147 541.870983 9.97 10.26 17.009 0.028 0 550.862006 0.28 4.32 17.036 0.012 0 Note: If one of the time, magnitude or magnitude uncertainty are not positive values that entry will be considered invalid and ignored. As long as they remain positive you may normalize the time an magnitudes. This means that you can use arbitrary units and zero point (i.e. multiply by and/or add a constant). Obviously, the given period and the output results will be transformed in the same manner.
