\title{Identifications for Baade's Variables}
\vskip -5mm
\title{in Sagitta and Cygnus}
\vskip -3mm

\begintext

     The tables below show identifications and precise positions for a group of
variables found by Walter Baade (1928) during his Bergedorfer days.  The stars
reported in this survey are of some historical interest because it was as a
result of this work that Baade conceived ideas that led to his later
recognition of the two stellar populations among Galactic stars ({\it cf}.
Osterbrock 1995).

     The paper is one of the few variable-star surveys where precise positions
are supplied (for equinox 1925), so checks and identifications were easy to
make in modern catalogues.  I examined each star on the digitized sky survey
using the Goddard SkyView facility (Scollick 1997).  Baade's original positions
in his Table 1 are very good, all less than 2\farcss\, from FK5-system
positions, and often within 1\farcss.  In the Cygnus field (Table 2), they are
somewhat less good, but still within about 3\farcs5.  In either case, making
identifications on the sky is unambiguous despite the absence of finder charts.
Follow-up lightcurves and photometry of comparison stars with finding charts
for several of Baade's short-period variables can be found in Henden (1996) and
Schmidt \& Seth (1996).

     The stars are listed in the same order as in Baade's tables.  The first
column shows the provisional ``Kiel'' designation used in the
{\it Astronomische Nachrichten}\, (Baade did not give all of these).  Next
comes the proper variable-star name, taken directly from the machine-readable
version of volume 4 of the GCVS4 available from the Strasbourg CDS ftp service.
N.B. the mix of O's and Q's among the names in Table 2.  Since few of the stars
appear in the GSC, I have by preference extracted positions from the U. S.
Naval Observatory UJ1.0 star catalogue (Monet {\it et al}. 1996a), or the more
comprehensive A1.0 catalogue (Monet {\it et al}. 1996b).  The few remaining
positions were taken directly from Baade, or estimated to $\pm$2\farcss\, using
SkyView.  The source of the position is coded as follows: A = A1.0, B = Baade,
S = SkyView, U = UJ1.0.

Notes to Table 1:

SY Sge\quad\enskip HD 350944 = LS~II~+18\degr17.

DO Vul\quad\enskip no star on DSS precisely at Baade's position.  The Downes
     \& Shara (1993) dwarf-nova 
\hspace*{15mm} atlas identifies this as the northwestern
     star of a faint pair at position end-figures 10\fss9/43\farcss.
\hspace*{15mm} The identification is uncertain, however, since there have been
      no outbursts reported in 
\hspace*{15mm}the modern literature.

NSV 12528\quad\enskip BSNS 32.

AN 48.1928\quad\enskip NGC 6838~V2 = Cl* NGC 6838~ZDA 16.

NSV 12675\quad\enskip equal $\sim\!4$\farcss\, pair on DSS, resolved in UJ1.0.
     Baade's position is close to the mean of
\hspace*{15mm}  the two, which was adopted.

NSV 12597\quad\enskip evidently the southwestern star of a merged pair on DSS.
     The position (from Baade)
\hspace*{15mm}  given by Richter \& Greiner (1996) is in error
     by +10\farcss; they identify the northeastern star
\hspace*{15mm}  of the pair as the  variable.

NSV 12606\quad\enskip excellent IRAS position match, but the [12--25] color is
     relatively blue.
