This is meant to be an introduction to what parts of the codebase run during a solve.
A field to solve is encapsulated in an “axy” file, which is a FITS binary table containing X,Y star positions, and well as FITS header cards that describe the command-line arguments and other information we have about the image. “axy” is short for “augmented x,y list”, and we often abbreviate “x,y list” to “xylist”. augment-xylist.c creates these “axy” files.
This is the astrometry-engine executable.
Runs a set of fields with a set of index files.
Runs a single field with a set of index files.
