Abstract

Measurements of narrow bands (Jn, Kn, Ln) magnitudes for 176 stars made at the Observatorio del Teide, Tenerife, are presented together with probable errors. Tests of the probable errors are given. Transformation between these narrow band magnitudes and Johnson magnitudes are proposed.

Transformation to JKL Johnson

V-J = -0.044 + 0.988 (V - Jn)
V-K = -0.020 + 0.989 (V - Kn)
V-L = -0.038 + 0.981 (V - Ln)
