Capitalize names are official IAU names. For other craters the informal convention is to list the region of the planet followed by the crater's longitude, i.e., ovda106. Confidence level 3 objects, which probably aren't craters but cannot be ruled out as such, are given the same name zzz. Error is 0.05 . Error is 0.05 at the equator.
Value is actually diameter of a circle with an area equivalent to the crater's.
We measured the area digitally by outlining the rim and counting the number of enclosed pixels. For craters with terracing, the rim is defined by the outermost boundary of the observable terraces. In most cases the end result is nearly the same. Value is the density of craters in the neighborhood of the specified crater. A representative location in the crater floor is similar in brightness to the majority of the crater floor.
