RTGM calculations in OpenSHA are managed through an RTGM object that has a sole static create(HazardCurve?) method and several instance methods for retrieving calculation data (e.g. riskCoeff()). Tests are based on NHSMP hazard curves at each of the 34 NEHRP test cities at 5hz and 1hz spectral accelerations for site class B/C (vs760). Original matlab code from Nico and utilities to generate test result sets are contained in the org.opensha.sra.rtgm test directory.
Several static interpolation functions and tests were developed in conjunction with and support of RTGM. This preform no argument checking and are not fit for public consumption. However, the interpolation code in the OpenSHA function library is repeated in numerous locations and should probably be relocated to single, isolated, and individually testable methods.
