Re:NGC 1550
NGC 1550 was examined by Sun et al. (2003), with two ACIS-I observations. Now
with two additional longer ACIS-S exposures in the offset positions, the gas
properties in this system can be constrained much better. NGC 1550's temperature
profile is among the best determined for 1 keV groups, with the good Chandra
coverage. We can compare our results with those from G07 who analyzed two short
ACIS-I observations and an XMM-Newton observation. The temperature profiles
agree well, although we constrain the temperature to larger radii from the
ACIS-S observations. Our r_500_ and M_500_ are 10% and 50% higher than those
derived by G07. Our c_500_ (4.93^+0.50^_-0.46_) is smaller than G07's (9.0 +/-
0.6).
