= Normalized Cross-Correlation Evaluation =

This page describes the methodology for using normalized cross-correlation to evaluate a region of the model.

Cross-correlation is performed on the following images:
 * Model: Image of bigmap
 * Truth: Image of Zmaps

Images are generated using the following set of dirty sumfiles at the required resolution:
||||'''Spacecraft'''||||'''Sun'''||
||'''Azimuth (deg)'''||'''Zenith (deg)'''||'''Azimuth (deg)'''||'''Zenith (deg)'''||
||0||30||90||45||
||90||30||90||45||
||180||30||90||45||
||270||30||90||45||
||0||30||270||45||
||90||30||270||45||
||180||30||270||45||
||270||30||270||45||
||45||10||270||10||

 * Spacecraft Azimuth (degrees): 0, 90, 180, 270, 0, 90, 180, 270, 45
 * Spacecraft Zenith (degrees): 30, 30, 30, 30, 30, 30, 30, 30, 10
 * Sun Azimuth (degrees): 90, 90, 90, 90, 270, 270, 270, 270, 270
 * Sun Zenith (degrees): 45, 45, 45, 45, 45, 45, 45, 45, 10

Images resolution is chosen from the following based on the state of the model:
 * Resolution: 120cm, 75cm, 35c,m 18cm, 9cm, 5cm.
