Description: NIR images in the J, H, and Ks wave bands of L988e were first obtained by the authors on 2002 October 26 using the Simultaneous Quad Infrared Imaging Device (SQIID), which houses four 1024x1024 InSb arrays, of which only 512x512 are used, on the 2.1m telescope at the Kitt Peak National Observatory, a facility of the National Optical Astronomical Observatory. Higher spatial resolution, deep, NIR observations in the J (1.25um), H (1.65um), and Ks (2.15um) wave bands were obtained on 2004 July 6 with the Palomar Widefield IR Camera (WIRC), which houses a 2048x2048 HgCdTe array.
