3.The software should be developed using C language on a UNIX based system
4.The matrix diagonalisation routine should zero out all off-diagonal elements, which are equal to or less than 10-3
5.Experienced officers should be able to use all the system functions after a total training of two hours. After this training, the average number of errors made by experienced officers should not exceed two per day.
