NGC 807. This is an isolated giant elliptical galaxy at a distance of 64
Mpc. HI has been observed by Dressel (1987), using both the Arecibo
antenna and the VLA. The inferred HI mass is 6.2 x 10^9^ M_sun_, and the
HI linewidth is 510 km s^-1^. The HI velocity field is consistent with
circular disk rotation. We derive an H_2_ mass of 1 x 10^9^ M_sun_. The
CO profile has a width of 490 km s^-1^.
