This program checks for NULL tracks in the seven tracks of a Viking image cube. If the percentage of pixels in a line of a track meets or exceeds the THRESHLD value, then that track is considered bad and the program will replace all NULL values in that track. It does this replacement by using valid pixels from each side of the track to perform an interpolation to calculate the new pixel value.

This example shows the vikfixtrx application. The threshhold percentage value is defaulted to 90.0.
