L 1498 maps of continuum, extinction, and line integrated intensity. The CFHT NIR maps at the (a) J band, (b) H band, and (c) K_s band. Spitzer MIR maps at (d) IRAC1 band, (e) IRAC2 band, and (f) IRAC4 band with its contours at 7.0 MJy sr⁻¹. (g) Visual extinction map with a beam size of 50″ with contours at 2.5, 5, 10, 15, 20, 25 mag. (h) JCMT SCUBA-2 850 µm map with a beam size of 14″ and the contours shown in Fig. 1. (i) Integrated intensity maps of N₂H⁺ J=1–0 from Tafalla et al. (2004), calculated within V_LSR=[−0.5 km s⁻¹, 15.2 km s⁻¹] with its contours at 20, 40, 60, 80% of its peak at 2.5 K km s⁻¹ and a beam size of 26″. The central cross in each panel indicates the center of L 1498. The scale bars of 0.05 pc and A_V/millimeter-wavelength beam sizes are denoted in the bottom right and bottom left corners, respectively.
