Interstellar Extinction Law toward the Galactic Center III: J, H, Ks bands in the 2MASS and the MKO systems, and 3.6, 4.5, 5.8, 8.0 micron in the Spitzer/IRAC system
Shogo Nishiyama,Motohide Tamura,Hirofumi Hatano,Daisuke Kato,Toshihiko Tanabe,Koji Sugitani,Tetsuya Nagata +6 more
TL;DR: In this paper, the authors determined the extinction law toward the Galactic center (GC) at the wavelength from 1.2 to 8.0 micron, using point sources detected in the IRSF/SIRIUS near-infrared survey and those in the 2MASS and Spitzer/IRAC/GLIMPSE II catalogs.

INTERSTELLAR EXTINCTION LAW TOWARD THE GALACTIC CENTER III: J, H, KS BANDS IN THE 2MASS AND THE MKO SYSTEMS, AND 3.6, 4.5, 5.8, 8.0 μm IN THE SPITZER/IRAC SYSTEM
Shogo Nishiyama,Motohide Tamura,Hirofumi Hatano,Daisuke Kato,Toshihiko Tanabe,Koji Sugitani,Tetsuya Nagata +6 more
TL;DR: In this paper, the authors used color-magnitude diagrams (CMDs) to obtain the total-to-selective extinction ratios for the four IRAC bands, i.e., 3.6, 4.5, 5.8, and 8.0 μm.

TL;DR: In this paper, the average of the ratios of total to selective extinction in the near-infrared bands (J,H,Ks) toward the Galactic center from the observations of the region l 20 and 05 b 10 with the IRSF telescope and the SIRIUS camera was determined.
