J/A+A/332/L53       The PL relation of galactic carbon LPVs   (Bergeat+ 1998)

The PL relation of galactic carbon LPVs. The distance modulus to LMC Bergeat J., Knapik A., Rutily B. <Astron. Astrophys. 332, L53 (1998)> =1998A&A...332..L53B (SIMBAD/NED BibCode)
ADC_Keywords: Stars, carbon ; Parallaxes, trigonometric Keywords: stars: AGB and post-AGB; stars: carbon; stars: fundamental parameters; galaxies: distances Description: The estimated true parallaxes of 115 carbon LPVs and their unbiased y-values (see Sect. 4) for a study of the period-luminosity relation. The tables contains the entry in the cited Stephenson's catalogue (1989, Cat. III/156), the log of the period in days, the absolute magnitude in the K-band, the y-quantity as defined in Sect. 4, the difference between the estimated true parallax and the observed one, the estimated true parallax, the square root of the weight (times 100) of every used y-value for Sample 1 PL-relation (Sect. 4) and the classification into three samples (see Subsec. 3.1).
