PSP is MARIN's Propeller Series program.

The diagrams of the Wageningen series were made available long ago by the N.S.M.B. in the form of large scale diagrams. This large scale was necessary to obtain the required accuracy of the readings.

The USB Key-card stick, delivered with this book, contains the latest version of the polynomials. In a way the use of the program is equivalent to reading the diagrams. This makes it possible to use small scale diagrams, such as provided in this book, without reduction of the accuracy. The layout of the screen is such that the program also replaces the alternative diagrams such as the Bp - delta diagrams.

PSP runs on PC under Windows.
