Output files base-ngc.png an annotation of the image. base.wcs a FITS WCS header for the solution. base.new a new FITS file containing the WCS header. base-objs.png a plot of the sources (stars) we extracted from the image. base-indx.png sources (red), plus stars from the index (green), plus the skymark (“quad”) used to solve the image. base-indx.xyls a FITS BINTABLE with the pixel locations of stars from the index. base.rdls a FITS BINTABLE with the RA,Dec of sources we extracted from the image. base.axy a FITS BINTABLE of the sources we extracted, plus headers that describe the job (how the image is going to be solved). base.solved exists and contains (binary) 1 if the field solved. base.match a FITS BINTABLE describing the quad match that solved the image. base.kmz (optional) KMZ file for Google Sky-in-Earth.
