Adopt asymetric LDD error (LDD_lo, LDD_hi) like GAIA DR3

[bourgesl]

As log(LDD) is a Gaussian distribution, it means LDD is a log-Normal distribution.

In supplement of giving (standard error e_LDD), values LDD_lo / LDD_hi can be given too (asymmetric error) like GAIA:

radius_flame_lower : Lower confidence level (16%) of radius_flame (float, Length & Distance[Solar Radius])

Lower confidence level (16%) of the radius of the star from FLAME, see description for radius_flame. It is derived from teff_gspphot, lum_flame and associated uncertainties. It is defined as the 16th percentile value of the distribution from sampling. Upper and lower levels include 68% confidence interval.

radius_flame_upper : Upper confidence level (84%) of radius_flame (float, Length & Distance[Solar Radius])

Upper confidence level (84%) of the radius of the star from FLAME, see description for radius_flame. It is derived from teff_gspphot, lum_flame and associated uncertainties. It is defined as the 84th percentile value of the distribution from sampling. Upper and lower levels include 68% confidence interval.
