Notes for object NGC 0668

3 note(s) found in NED.


1. 1997A&AS..126..537B
Re:NGC 0668
NGC 668 is a bright spiral (Sb) located at a relatively large projected
distance from the cluster center (81'). The signal-to-noise ratio of this
detection is low because of its large distance (nearly 22') from the pointing
center. The first contour in Fig. 1 is 4.7 10^20^ cm^-2^. More sensitive
measurements are needed to confirm the observed irregular distribution.

Re:NGC 0668
NGC 668: The continuum isophotes to the South must be considered with
care because parasitic light affecting this exposure can be only very
roughly subtracted.
Although the H{alpha} emission is much brighter and more extended
toward the South, the rotation curve is fairly symmetric and can be
followed as far to the north as to the south.
