Scientific paper

The catalog of single-period RR Lyraes is composed of two tables, one for each field:
- filed1.dat for variables detected in field 1 (SAG) centered on (l,b)=(6.6°, -10.8°). The photometry of these RR Lyraes is based on a combination of a Kodak Tech-Pan 4415 film with a BG12 filter.
- field2.dat for variables detected in field 2 (DUO) centered on (l,b)=(3.1°, -7.1°). The photometry is based on the Bj system.
It is important to note that the photometric systems are different between the two fields (see paper I & II for details). The magnitude and amplitude are therefore not directly comparable from one field to another.
The RR Lyrae stars of this catalog are almost evenly distributed between the Sagittarius dwarf and the Galaxy. They are easily separated through an histogram of the magnitudes (see Paper I).
