   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.
