Figure 10 - Comparison of 2MASS Combined Calibration Field and SDSS images in the 2MASS 90004 Calibration field

Rolling the cursor over the image switches between a composite (J/H/K_s) image made by combining approximately 1400 independent observations of the 2MASS 90004 calibration field, and a composite (g'/r'/i') image of the same region from the Sloan Digital Sky Survey. The images cover an 8'x8' region."
