The measured transmissions of the MKO near-infrared consortium filters mounted in NICS are displayed in Fig. 1 which also includes, for comparison, the curves relative to the standard J filter (see the caption for details). The corresponding half-power points and average transmissions are summarized in Table 1.
Figure 2 is a zoom on the transmission curves of the narrow band filters and includes measurements taken at different incidence angles. The shift of the central wavelength and half power points can be well represented by the relationship
