======================================================================= A Low-Resolution Spectroscopic Exploration of Puzzling OGLE Variable Stars P. Pietrukowicz, M. Latour, R. Angeloni, F. di Mille, I. Soszynski, A. Udalski, C. Germana ======================================================================= pietruk@astrouw.edu.pl This directory contains details on magnetic stars (alpha2 CVn type, ACV) identified in the OGLE-III Galactic disk (GD) fields and recently confirmed spectroscopically. The directory structure is as follows: README - this file ident.dat - identification of stars acv.dat - parameters of the objects phot/I/ - I-band photometry of individual objects phot/V/ - V-band photometry of individual objects phot.tar.gz - gzipped phot/ directory fcharts/ - finding charts for individual objects spectra/ - low-resolution spectra of some objects pap.pdf - PDF version of the paper Pietrukowicz et al. (2015), Acta Astron., 65, 63, (arXiv:1503.03499) describing this result Format of the file ident.dat: -------------------------------------------------------------------------- Bytes Format Units Description -------------------------------------------------------------------------- 1- 15 A15 --- Star's ID in the form OGLE-GD-ACV-NNN 18- 25 A8 --- OGLE-III field 27- 32 I6 --- OGLE-III database number 35- 36 I2 h Right ascension, equinox J2000.0 (hours) 38- 39 I2 m Right ascension, equinox J2000.0 (minutes) 41- 45 F5.2 s Right ascension, equinox J2000.0 (seconds) 47 A1 --- Declination, equinox J2000.0 (sign) 48- 49 I2 deg Declination, equinox J2000.0 (degrees) 51- 52 I2 arcmin Declination, equinox J2000.0 (arc minutes) 54- 57 F4.1 arcsec Declination, equinox J2000.0 (arc seconds) -------------------------------------------------------------------------- Format of the file acv.dat: -------------------------------------------------------------------------- Bytes Format Units Description -------------------------------------------------------------------------- 1- 15 A15 --- Object's ID in the form OGLE-GD-ACV-NNN 18- 22 F5.2 mag Mean V-band magnitude 24- 28 F5.2 mag Mean I-band magnitude 31- 35 F5.2 mag I-band amplitude 38- 46 F9.6 days Period 49- 56 F8.6 days Uncertainty of the period 59- 61 A2 --- Spectral type -------------------------------------------------------------------------- Finding charts are gzipped Postscript images. The names of the files are in the form: OGLE-GD-ACV-NNN.ps.gz. The finding charts are 60"x60" subframes of the I-band reference frames centered on the star. White cross marks the star. North is up and East to the left. Any presentation of the scientific analysis or usage of the data from the OGLE catalog of variable stars should include appropriate references to OGLE papers.
