Yale/San Juan SPM4 Catalog
The SPM4 Catalog contains absolute proper motions, celestial coordinates,
and B,V photometry for 103,319,647 stars and galaxies between the south
celestial pole and -20 degrees declination. The catalog is roughly
complete to V=17.5. It is based on photographic and CCD observations
taken with the Yale Southern Observatory's double-astrograph at Cesco
Observatory in El Leoncito, Argentina.

These flags indicate the source of the magnitude given:
=== ======================================================
1 magnitude came from the compiled input catalog
2 magnitude was based on 1st-epoch SPM plates
3 magnitude was based on 2nd-epoch SPM CCD observations
=== ======================================================
If the number of CCD frames used in the second epoch is larger
than 9, this column still contains 9.
Note that if both the number of plates and the number of CCDs
for second epoch are zero, the 2nd-epoch position used to calculate
the proper motion was adopted from the input source catalog.
=== =======================================================
0 no indication the object is non-stellar.
1 the object is a 2MASS extended source.
2 the object is a LEDA confirmed galaxy.
3 the object is from the Veron-Cetty & Veron QSO catalog.
=== =======================================================
The catalog the input object was taken from is encoded as follows
(for objects in multiple catalogs, the first (lowest number)
catalog identification is retained):
== ==========================================
1 Hipparcos.
2 Tycho-2.
3 UCAC2.
4 the 2MASS point source catalog (psc).
5 the 2MASS extended source catalog (xsc).
6 the LEDA galaxy catalog.
7 the Veron-Cetty & Veron QSO catalog.
