Geometry

Once we have finished tiling LMK000, we can solve for an updated geometry

GEOMETRY.e
- 1: landmark vectors
- 2: camera pointing, scobi
- 3: RA/DEC/TWIST
- 0: end
120 - input operation list
3 - enter number of iterations
n - change position and pointing aprioris? (y/n)

Residuals

After running GEOMETRY, we can solve for the residuals
Check for landmarks with poor residuals
possible misregistration => manually adjust

RESIDUALS.e
2,4,10 - enter plim (px,km,km)
Then look at MAPINFO.TXT, PINCINFO.TXT, RESIDUALS.TXT and fix any outliers in LITHOS
