Head -to-Tail Vector Plot Program (entitled PROGRAH NUWS ) 



This program (discussed in chapter III) prepares data punch cards from 

 current meter data (consisting of current vector speed and direction). 

 These cards are then placed in the Benson-Lehner electro -plotter^ which 

 plots the head-to -tail vector plot. 



The abbreviations used are the following : 



D = Direction of current (°T) 



S = Magnitude of vector (cm sec" ) 



L = / 1 signifies end of data
