Re:ESO 209- G 009
A9. ESO 209-9 The H{alpha}+[N IIl image of ESO 209-9 is shown in Figure
9. Little H{alpha} emission is detected anywhere in the galaxy, let
alone extended emission into the halo. This is the only galaxy in the
sample with no obvious signs of extraplanar line emission. The modest
flux limit (~2 10^-17^ ergs s^-1^ CM-2 arcsec^-2^) and spatial
resolution (in pc) may explain the apparent lack of EDIG in this object.

Re:ESO 209- G 009
ESO 209-9 This little studied nearby, southern edge-on galaxy has both
a moderate ratio of L_FIR_/D^2^_25_, and S_60_/S_100_. Its H{alpha}
morphology reveals an extended layer, not as prominent as in NGC 891 or
NGC 3044, but still quite intense. The distribution of the H{alpha}
emission is asymmetric which could be a projection effect, if we were
looking at the very end of the spiral arm to the south along the line
of sight, whereas the spiral arm to the north could be winded more
tightly. Quite extraordinary is an additional emission component, which
shows up in the whole field around ESO 209-9. We speculate that this
emission, which is shown in its fully covered extent in the
H{alpha}+continuum image (see Fig. 3), is of Galactic origin. Quite
remarkably, there is no hint of any filamentary emission in the broad
R-band image. Our first impression was that this could be stray light
from a bright star just outside the covered CCD field. However, as
there was neither a shift (after alignment) nor a change in the
emission pattern noticed in the two individual H{alpha} images, which
were offset by 20" from one another, and furthermore such structures
were never recorded prior or after these exposures in other object
frames, we suspect that these structures indeed have a Galactic origin.
A visual inspection of both the blue and red DSS images did not reveal
anything conclusive. Unfortunately, the IR DSS plate of the region
around ESO 209-9 is not yet obtained/digitized. The IRAS maps show some
emission in that area, however, the resolution is not sufficient enough
to resolve these structures clearly. A possible explanation could be,
that this emission is Galactic cirrus. This would not be unreasonable,
since ESO 209-9 has a galactic latitude of only b{approx} -11deg.
Unfortunately, this position is just outside the regions studied by the
AAO/UKST H{alpha} survey of the southern galactic plane (e.g., Parker
et al. 1999), which would have been a good test for comparison. It
could also be extended red emission (ERE) in the diffuse interstellar
medium. This ERE was found for high-galactic cirrus clouds by Szomoru &
Guhathakurta (1998). They found a peak of cirrus ERE at {lambda}~6000
{Angstrom}. However, in order to unravel the true nature of this
filamentary emission, this should be re-investigated by independent
deep H{alpha} images using a different instrumental setup, and
supplemental spectroscopy. Fortunately, very recently, we downloaded an
available H{alpha} image from the Southern H{alpha} Sky Survey Atlas
(SHASSA)(see Fig. 2), which became available very recently. For details
on SHASSA we refer to Gaustad et al. (2001). Indeed, the field around
the galaxy ESO 209-9 shows detectable H{alpha} emission, and the
H{alpha} morphology is clearly recovered, despite the spatial
resolution of the SHASSA is much lower than in our images.
