A search for stellar populations in high-velocity clouds. Siegel M.H., Majewski S.R., Gallart C., Sohn S.T., Kunkel W.E., Braun R. <Astrophys. J., 623, 181-195 (2005)> =2005ApJ...623..181S
ADC_Keywords: Photometry, CMT1T2V ; Photometry, DDO ; Molecular clouds Keywords: Galaxy: halo - ISM: clouds Abstract: We report the results of a photometric search for giant stars associated with the cores of four high-velocity clouds (HVCs) - two of which are compact HVCs - using the Las Campanas du Pont 2.5m and Cerro Tololo Blanco 4m telescopes in combination with a system of filters (Washington M, T2 + DDO51) useful for identifying low surface gravity, evolved stars. Description: The high-velocity clouds HVC 017-25-218, HVC 030-51-119, and HVC 271+29+181 were observed in the Washington C, M, and T2 filters, as well as the MgH+Mg b triplet sensitive DDO51 filter, on UT 2000 June 5-8. We used the du Pont 2.5m telescope and the Wide Field Camera (WFC). File Summary:

Note (1): [SMG2005] LLL-BB-VVV NNNNN and [SMG2005] LLL-BB-Ctl NNNNN in Simbad Note (2): The 4-meter data have no C imaging. Any values listed as 99.999 were unmeasured. Note (3): Non-variable stars would have values ≤1.0. The 4-meter data only have one observation in each filter and the variability indices are listed as 0.0. The stars from the 2.5-meter data generally have indices ≤1.0 indicating little variability over the three days of our observing program and agreement between the formal errors and empirical scatter of the photometric measures. Bright stars are occasionally saturated on the CCD images, resulting in elevated variability indices.
