b-) Comparison running the model Drimmel et al. (2003) on a local machine and using GALExtin for a list of 2,000 directions (l,b,distance).

- Marshall et al. (2006):

We did a query using Vizier-CDS for Galactic longitudes for l = 5.0°, 35.0°, 65.0°, 95.0°, 265.0°, 295.0°, 325.0°, 355.0° (Catalog: J/A+A/453/635/table1). File obtained.

This file contains data for |b| <= 10 degrees. All distances (d) are avalaible for each l.o.s.

From this file, we made a catalog with 7,190 points with only l,b,d,A_Ks. GALExtin results for these directions.

This file contains data for |b| <= 10 degrees. All distances (d) are avalaible for each l.o.s.

From this file, we made a catalog with 790 points with only l,b,d,E(J-Ks),E(H-Ks). Negative values mean no data. GALExtin results for these directions.
