The All-Sky Portable (ASP) optical catalog  (2017, PASA 34, 25) 


The ASP (All-Sky Portable) catalog presents 1,163,237,190 optical objects in 100 files of 9Gb total download size.  Fields are RA and Dec J2000 to tenth-of-arcsecond precision, red-blue photometry which yield magnitudes to a hundredth-of-magnitude precision, PSFs and variability indicator, and flags for proper motion, survey epoch, photometry source survey & catalog, and astrometry source survey & catalog.  Full details are in the paper and ReadMe.  ASP was published as 2017, PASA 34, 25. 

Here is the pre-print paper for the catalog.   

Here is the ReadMe , essential for its field descriptions and sample computer code (in BASIC and Python) to process the fields.
