Data and Headers Coordinate Systems

The History File contains the usual SEPlib77 parameters ni, oi, di, labeli (where i=[1,2,3,...]) describing the Data Coordinate System. The length of the axes in the Data Coordinate System must be constant and is given by the values of the respective ni parameter. The number of data values in a data record is given by n1 and the the number of data records is equal to the product $({\tt n2*...*n{\it i}*...})$.

The Header Format File also contains the usual SEPlib77 parameters ni, oi, di, labeli (where i=[1,2,3,...]) describing the Header Coordinate System. The number of header keys in the header records is given by n1 and the the number of header records is equal to the product $({\tt n2*...*n{\it i}*...})$.
