Notes:
For ACTIVE SNe we should orient the slit along the paralactic angle. However,
if the SN is located close to the host it might be necessary to pick a different
and more convenient angle to avoid contamination of the host. If so, it would
be convenient to observe the SN at a low airmass. The finding chart and coordinates
can be found | HERE | .
For OLD SNe, we need to orient the slit along the semi major axis of the host galaxy, using the
ANGLES and
CHARTS
provided by Ricardo Covarrubias. If you want to know which SN corresponds to the displayed
image, put the cursor on it without clicking. If you want to see an enlarged image
