FGL 2 DX Cha. Hen 3-741. Noted as possible binary (separation > 0".040) by
Baines et al. (2006) Bns2006
In eps Cha Association. 11596-7813 is also a member.
11596-7813C = 12001-7812A.
B, C, D, and E components were resolved by Feigelson et al. (2003) Fgl2003
using Chandra ACIS-I (Advanced CCD Imaging Spectrometer Imager).
Additional wide components G, H, I, J, and K, as well as closer F
companion were resolved by Grady et al (2004) using data from HST/STIS Gry2004
and VLT/NACO. Their theta values for AD and AE appear to be in error;
correct values are perhaps 180-71=109deg and 180-74=106deg?
Grady et al. provided no relative astrometry for the H, I, J, and K
companions. Coarse values were extracted by the cataloguer using
Aladin, based on their Figure 4.
