Calar Alto Deep Near-IR Images
Downloads:Coming Soon... |
Pretty Pictures:Large JPEGs of L1448 and L1451 as they will appear in ApJ Letters. L1448  L1451 
Color images made with xdimsum images, DS9, and Photoshop. | |||
Description:Deep near-IR images (J,H,Ks) taken to produce high-resolution extinction maps. Regions neer dense clouds show some extended emission (cloudshine) which we believe to be Galactic starlight scattering off dust. One region, L1448, shows a number of remarkable outflows. |
||||
Comments on Reduction:Cloudshine complicates data reduction. Regions covered by extended emission will be dimmer than in reality, since sky-subtraction will subtract out real signal. This process acts like a sharpening filter, enhancing contrast in these images. |
