    2MASS Magnitude Limits

    from the 2MASS Level 1 Science Requirements

    (For unconfused sources outside of the Galactic Plane (|b|>10°), and outside of any confusion-limited areas of the sky outside of the Galactic Plane.)

    Magnitude Limits
    Band Wavelength (µm)Point Sources (SNR=10) Extended Sources
    J1.2515.815.0
    H1.6515.114.3
    Ks2.1714.313.5

    Note: At SNR=10, sigma(mag) = 2.5 / ln 10 = 0.109. Also, the feasibility of the point source requirement at H is uncertain, due to lack of knowledge of background variations.
