Detailed Description

This is based on the tables given in Moller95 and Moller97. To load data from the O2scl HDF5 data files, use o2scl_hdf::mnmsk_load().

The data containing an object of type entry for 8979 nuclei is automatically loaded by the constructor. If the file (nucmass/mnmsk.o2) is not found, then is_loaded() will return false and all calls to get_ZN() will return an object with N=Z=0.

There are several entries in the original table which are blank because they are in some way not known, measured, or computable. To distinguish these values from zero, blank entries have been replaced by the number 1.0e99. For convenience, this value is returned by blank().

Note: This class requires data stored in an HDF file and thus requires HDF support for normal usage.

Member Function Documentation

◆ get_ZN()

nucmass_mnmsk::entry o2scl::nucmass_mnmsk::get_ZN	(	int	l_Z,
		int	l_N
	)

This method searches the table using a cached binary search algorithm. It is assumed that the table is sorted first by proton number and then by neutron number.

◆ set_data()

int o2scl::nucmass_mnmsk::set_data	(	int	n_mass,
		nucmass_mnmsk::entry *	m,
		std::string	ref
	)

This function is used by the HDF I/O routines.

The documentation for this class was generated from the following file:
