JHK imaging photometry of Tr 14, Tr 15 and Tr 16

We have observed the areas associated with the young open clusters Tr 14, Tr 15 and Tr 16 of the Eta Carinae Region in the near-infrared (J, H and K'), using a NICMOS 3 array detector (256 x 256 pixels) and the Swope lm telescope of Las Campanas Observatory. The images are sampled to 0.45 arcse...
