Detailed Description

Auxiliary functions for SEOBNRv1/v2 reduced order modeling codes in LALSimIMRSEOBNRv2ROMDoubleSpin.c, LALSimIMRSEOBNRv1ROMDoubleSpin.c, LALSimIMRSEOBNRv2ROMEffectiveSpin.c, LALSimIMRSEOBNRv1ROMEffectiveSpin.c, LALSimIMRSEOBNRv2ChirpTime.c, LALSimIMRSEOBNRv2ROMDoubleSpinHI.c.

Author: Michael Puerrer

Here I collect common auxiliary functions pertaining to reading data stored in gsl binary vectors and matrices, HDF5 files using the LAL interface, parameter space interpolation with B-splines, fitting to a cubic, a custom gsl error handler and adjustment of nearby parameter values.
