Re:NGC 5380
NGC 5378 and 5380: in principle, our Nancay profiles of these two galaxies
are expected to be mutually confused, as they are separated by 11.4'
(about half a HPBW) in the N-S direction. As NGC 5380 has been classified
as an elliptical/S0 in various catalogues, we do not expect to detect it
in H I; an upper limit of 1.26 Jy km s^-1^was reported for NGC 5380 at
Arecibo (Chamaraux et al. 1987), where the 3.6' HPBW should not cause any
confusion with NGC 5378. In fact, our detections towards the centres of
both objects show strikingly similar profile parameters, indicating they
are in fact both detections of the spiral NGC 5378. For their Nancay
profile, Theureau et al. (1998), who assumed it to be confused with
NGC 5380, listed only a central velocity (2715 km s^-1^), which is about
260 km s^-1^ lower than that of the other two spectra. However, our
measurement of the central H I velocity from the spectrum of Theureau
et al. is 2990 km s^-1^, in agreement with the other two spectra, and the
linewidths we measured from their spectrum (see Table 6) are in agreement
with our Nancay values. The integrated line flux we estimated from the
plotted spectrum, ~3.9 Jy km s^-1^, is in also agreement with our value.
Therefore, only the values measured by us from the Theureau et al.
spectrum have been listed in Table 6. On the other hand, the line flux of
NGC 5378 measured at Green Bank by Richter & Huchtmeier (1991),
11.2 Jy km s^-1^, is much higher than the Nancay values and their profile
widths about 40% larger. This Green Bank profile is not expected to be
confused by NGC 5380, given the telescope's HPBW, nor are any other
galaxies visible in its vicinity. A broad RFI signal seems the only
plausible cause of the striking discrepancy between the Green Bank and
Nancay profiles.

The envelope that begins at what appears as
an edge to the inner bulge of NGC 5380 is
prominent on the plate. It can be seen best on this
print when viewed from a distance by moving the
head or eyes.
