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).
