Method Detail

locatePixel

public double locatePixel(AbsoluteDate date)
                   throws RuggedException

Locate pixel along sensor line.

Parameters:

date - current date

Returns:

pixel location (Double.NaN if the first and last pixels of the line do not bracket a location)

Throws:

RuggedException - if the maximum number of evaluations is exceeded
