3D reddening map for stars from 2MASS phot.
Listed in IVOA Registry (Virtual Observatory)
A three-dimensional reddening map for stars within 1100pc of the Sun are presented.
Description
Analysis of the distribution of 70 million stars from the 2MASS catalog with the most accurate photometry on the (J-Ks)-Ks diagram supplemented with Monte Carlo simulations has shown that one of the maxima of this distribution corresponds to F-type dwarfs and subgiants with a mean absolute magnitude M_Ks_=2.5m. The shift of this maximum toward large (J-Ks) with increasing Ks reflects the reddening of these stars with increasing heliocentric distance.
The distribution of the sample of stars over Ks, l, and b cells with a statistically significant number of stars in each cell corresponds to their distribution over three-dimensional spatial cells. As a result, the reddening E(J-Ks) has been determined with an accuracy of 0.03m for spatial cells with a side of 100pc. All of the known large absorbing clouds within 1100pc of the Sun have manifested themselves in the results obtained.

The absorbing matter of the Gould Belt is shown to manifest itself at latitudes up to 40{deg} and within 600pc of the Sun. The size and influence of the Gould Belt may have been underestimated thus far. The absorbing matter at latitudes up to 60{deg} and within 1100pc of the Sun has been found to be distributed predominantly in the first and second quadrants in the southern hemisphere and in the third and fourth quadrants in the northern hemisphere.
The E(B-V) should be used together with Rv from Gontcharov (2012AstL...38...12G, Cat. J/PAZh/38/15) and Av from Gontcharov (2012AstL...38...87G, Cat. J/PAZh/38/108).
