no_update.txt

Description

This text file lists landmarks output by residuals whose associated pictures are not listed by increasing mission time in the .LMK file.

residuals checks the .LMK file for each landmark listed in LMRKLIST.TXT for pictures that are not listed in ascending order. Since the image name is based on ephemeris time, ascending order is a proxy for increasing time. Therefore, deviations from ascending name order show images that are not listed based on increasing mission time. These landmarks are then listed in no_update.txt.

Here is a sample of a .LMK file for which the landmark would be listed in no_update.txt:
