FHUFD (HST Proposal #12549) is a deep, high-precision, photometric survey of six ultra-faint dwarf galaxy satellites of the Milky Way, in order to discern any cosmologically-driven synchronization of their formation histories. For six ultra-faint dwarf satellites of the Milky Way (Bootes I, Coma Berenices, Canes Venatici II, Hercules, Leo IV, and Ursa Major I), the team provides ACS photometry, astrometry, and co-added (drizzled) images. The photometry and images are in two bands: F606W (broad V) and F814W (I), using the STMAG photometric system. The astrometry is given in equatorial coordinates (degrees, J2000). The drizzled images have a scale of 0.03 arcsec/pix. The images from each pointing are contained in their own FITS files. Each galaxy also has a single catalog file containing the point sources detected in the images.
<##> = the pointing number, as a two-digit zero-padded integer
<filter> = the filter used, either "f606w" or "f814w"
The source catalogs follow a similar naming convention, except there is no pointing number component, and the string "multi" is used instead of the filter. The extension for the source catalogs is "*cat.fits".
