Interactive 2MASS Image Service

This service enables rapid interactive viewing and retrieval of a single 2MASS Image set (J, H, and K_s). The desired image can be specified based on position, target object name, or one of several image parameters. In the case of an image requested by position or object name, if more than one 2MASS Image covers the target, the image returned is the image on which the target is best centered. A listing of all 2MASS Images covering a specific position or object can be obtained by using the 2MASS Image Inventory Service.

CAUTION: Always use 2MASS Atlas Images for photometric measurements - 2MASS Quicklook Images are restored from lossy-compressed files.

For a detailed explanation of all the retrieval modes and options provided by this service, please visit the Interactive 2MASS Image Service Help web page.
