Message:

Add new recipe values PSASTRO.GRID.MIN.INST.MAG.RAW and PSASTRO.GRID.MAX.INST.MAG.RAW to control
the range of magnitudes used for grid search. For STS_DATASET recipe use the magnitude range
-15 -11 for the grid search and tighten it up to -12 -11 for fitting. This avoids the bright
star problem
