Example of dataset for poisson_kriging.exe. Data for the Poisson kriging program must be in Geo-EAS format. The first line is the name of the data file. The second line should be a numerical value specifying the number of variables (i.e. nvar columns) in the data file. The next nvar lines contain the name of each variable. The following lines, until the end of the file, are considered as observations and must have nvar numerical values per line.
