Also systematical errors were investigated and methods were developed to minimize the effects.The code is explained in The coding of the mask for CCD_Rasnik by H.L.Groenstege from NIKHEF. This is a NIKHEF paper, registered in 1994, numbered ETR_94-10. This paper can be obtained from NIKHEF or can be downloaded as a .PDF.We claim all rights on using the principle and methods, especially on the coding of the mask (lightsource).
