NED object is Arp 205; Reference is 1979MNRAS.187..509R
Figure 4. Low-resolution integrated HI map of Arp 205 incorporating 19
continuum-free output maps over the velocity range 1082-1556km per second. The
HPFW resolution of 7.4 x 1O arcmin is shown by the hatched ellipse. The outer
dashed contour is 20 K km per second, while the first solid contour is at 50 K
km per second and higher contours are at intervals of 30 K km per second. The
noise on this map varies as the number of channels added at any point, but
should not exceed (19^1/2^) {sigma} = 20 K km per second. The shading
represents the regions of optical emission from the galaxies, the smaller
crosses are star positions (cf: Plate I), and the larger cross is at the map
centre.
