= SUMFILES = == Description == This directory stores '''sumfiles'''. A "sumfile" is created by the executable [[make_sumfiles]]. It contains the following information about its image: * camera data * target-relative position vectors * pointing vectors * uncertainty values * landmark info There is only one '''sumfile''' for each image. SPC uses data from '''sumfiles''' throughout various executables such as [[lithos]]. As you use SPC to correlate images with [[lithos]], you can update the '''sumfile''' vectors and landmark lists using the "v 4" command (see [[lithos]]). Unlike [[nominals]], '''sumfiles''' can change throughout SPC usage. The '''sumfiles''' crated by [[make_sumfiles]] are named as .SUM and placed in a directory titled '''SUMFILES''' within the user's working directory.
