JHK photometric system
(JHK, 2MASS photometric system)
(system to classify stars according to near-infrared colors)
The JHK photometric system (2MASS photometric system or JHK) is
a photometric system that
uses the J (1220 nm), H (1630 nm), and K (2190 nm)
passbands/filters to record the various colors
within the near infrared.
It was used by the Two Micron All-sky Survey (2MASS).
