J/AJ/112/772 J/AJ/112/772 VI photometry in South Galactic Pole J A R Caldwell P L Schechter Astron. J. 112 772 1996 1996AJ....112..772C Galactic pole, south Photometry, CCD The tables described below correspond to tables I-VII as mentioned in sections 5 and 6 of the printed paper. Catalogs of V and I photometry for two 20 square degree regions near the South Galactic Pole, containing 30,000 and 19,000 stars, have been constructed using a CCD in time delay integration mode. Internal and external comparisons indicate a characteristic photometric accuracy ranging from 0.02mag at V~12 to 0.05 at V~18-18.5.

CS CS star number (CS1 for table1; CS2 for table2) --- RAh Right ascension (1950) h RAm Right ascension (1950) min RAs Right ascension (1950) s DE- Declination sign --- DEd Declination (1950) deg DEm Declination (1950) arcmin DEs Declination (1950) arcsec Vmag V magnitude mag Imag I magnitude mag V-I V-I color index mag Code Four-digit code including number of V,I values A four-digit number gives from left to right: a first digit of 1 or 0 depending on whether or not the star was found to be a split star on any scan, a second digit for the number of V values, a third digit for the number of I values, and a last digit for the number of nearly simultaneous V and I values. --- e_Vmag V magnitude error mag e_Imag I magnitude error mag e_V-I V-I color error mag S s = split stars A split star has at least some contributory data where another star was sufficiently close that the "split star" method of solution (Schechter et al, 1993PASP..105.1342S) was invoked. --- U u = uncertainty because star is faint A "u" appears for stars so faint that the nonlinearity correction (Section 4 of the printed paper) was excessively uncertain. These were excluded from all use and are thus not included in the totals given in Table 2 of the printed paper. --- CS1 CS1 star number --- RAh Right ascension (1950) h RAm Right ascension (1950) min RAs Right ascension (1950) s DE- Declination sign (1950) --- DEd Declination (1950) deg DEm Declination (1950) arcmin DEs Declination (1950) arcsec Vcs CS V magnitude mag Ics CS I magnitude mag Ne Eriksson (1978UppOR..11....1E) number --- Ve Eriksson (1978UppOR..11....1E) V magnitude mag B-Ve Eriksson (1978UppOR..11....1E) B-V color mag U-Be Eriksson (1978UppOR..11....1E) U-B color mag Ve-Vcs Eriksson - CS V magnitude difference Median (53 pts, 2 rej)=0.000+/-0.003, Median-based est. std. dev.=0.015 mag CS1 CS1 star number --- RAh Right ascension (1950) h RAm Right ascension (1950) min RAs Right ascension (1950) s DE- Declination sign (1950) --- DEd Declination (1950) deg DEm Declination (1950) arcmin DEs Declination (1950) arcsec Vcs CS V magnitude mag Ics CS I magnitude mag Nr Reid & Gilmore App. A number Reid and Gilmore, 1982MNRAS.201...73R, Appendix A (p. 93) --- Vr Reid & Gilmore App. A V magnitude mag B-Vr Reid & Gilmore App. A B-V color mag V-Rr Reid & Gilmore App. A V-R color mag Ir Reid & Gilmore App. A I magnitude mag Vr-Vcs R&G - CS V magnitude difference Median (25 pts, 5 rej)=0.006+/-0.005, Median-based est. std. dev.=0.020 mag Ir-Ics R&G - CS I magnitude difference Median (40 pts, 4 rej)=0.012+/-0.005, Median-based est. std. dev.=0.024 mag CS1 CS1 star number --- RAh Right ascension (1950) h RAm Right ascension (1950) min RAs Right ascension (1950) s DE- Declination sign (1950) --- DEd Declination (1950) deg DEm Declination (1950) arcmin DEs Declination (1950) arcsec Vcs CS V magnitude mag Ics CS I magnitude mag Nr Reid & Gilmore Tab. 7 number Reid and Gilmore, 1982MNRAS.201...73R, Table 7 (p. 87) --- Vr Reid & Gilmore Tab. 7 V magnitude mag Ir Reid & Gilmore Tab. 7 I magnitude mag Vr-Vcs R&G - CS V magnitude difference Median (32 pts)=-0.031+/-0.010, Median-based est. std. dev.=0.046 mag Ir-Ics R&G - CS I magnitude difference Median (29 pts, 2 rej)=-0.017+/-0.011, Median-based est. std. dev.=0.047 mag CS1 CS1 star number --- RAh Right ascension (1950) h RAm Right ascension (1950) min RAs Right ascension (1950) s DE- Declination sign (1950) --- DEd Declination (1950) deg DEm Declination (1950) arcmin DEs Declination (1950) arcsec Vcs CS V magnitude mag Ics CS I magnitude mag Nco Corben number Murray, Argyle and Corben, 1986MNRAS.223..629M (Cat. <I/129>) --- Vco Corben V magnitude mag B-Vco Corben B-V color mag V-Rco Corben (Cat. <I/129>) V-R color mag Ico Corben (Cat. <I/129>) I magnitude mag Vco-Vcs Corben - CS V magnitude difference Median (42 pts)=-0.004+/-0.004, Median-based est. std. dev.=0.019 mag Ico-Ics Corben - CS I magnitude difference Median (73 pts)=-0.002+/-0.001, Median-based est. std. dev.=0.010 mag CS1 CS1 star number --- RAh Right ascension (1950) h RAm Right ascension (1950) min RAs Right ascension (1950) s DE- Declination sign (1950) --- DEd Declination (1950) deg DEm Declination (1950) arcmin DEs Declination (1950) arcsec Src Source Source Key: ccd photometry: CS this work Tab. 1 p.e.photometry: Ca this work Tab. 4 Co Murray-Argyle-Corben (Cat. <I/129>) Er Eriksson (1978UppOR..11....1E) RA Reid-Gilmore (1982MNRAS.201...73R, App. A) R7 Reid-Gilmore (1982MNRAS.201...73R, Tab. 7) ptg.photometry: Ep Eriksson (1978UppOR..11....1E) KG Kuijken-Gilmore (1989MNRAS.239..605K) --- Vmag V magnitude mag Imag I magnitude mag CDS 1997Jan30AAS CD-ROM series, Volume 7, 1996 Lee Brotzman [ADS] 14-Aug-1996 J_AJ_112_772.xml
