Abstract:
We measured the K-band luminosity function using a complete sample of
4192 morphologically typed 2MASS galaxies with µKs=20mag/arcsec2
isophotal magnitudes 7<K20<11.25mag spread over 2.12sr.

Note (1): Based on the scatter in the two or more classifications for
the object.
Note (2): Considered to have either a B = Full bar, or a X = incipient bar,
by at least one classifier.
Note (3): Y = Considered peculiar or interacting by at least one classifier.
