IRS SL, LL, SH, and LH slit positions (only one of the two nod positions is shown) superposed on the NICMOS J‐band (F110W) image of DG Tau B from Padgett et al. (1999); note that for this object the LL module was not used and is shown for illustrative purposes only. The slits, with their different widths and orientations, cover different parts of the object.
