Syntax:
-rescalesig Example 1.$ ./vartools -i EXAMPLES/4 -oneline \ -chi2 -rescalesig -chi2 Name = EXAMPLES/4 Chi2_0 = 5.19874 Weighted_Mean_Mag_0 = 10.35137 SigmaRescaleFactor_1 = 0.43858 Chi2_2 = 1.00000 Weighted_Mean_Mag_2 = 10.35137
Rescale the formal errors in the light curve EXAMPLES/4 such that chi2 per degree of freedom equals 1. We call -chi2 before and after -rescalesig to demonstrate that this rescaling has been done. Note the subtle difference from the -changeerror command which replaces the formal errors with the RMS of the light curve.
