Given a multispectral image with a DN covariance matrix,

.

What is the correlation matrix? Now, suppose you do a calibration of the data to at-sensor

radiance L as follows,

What are the covariance and correlation matrices of the calibrated data? Will the PCT of the

calibrated data be the same as the PCT of the DN data? Will the standardized PCT be the

same? Provide a mathematical and graphical explanation.
