IRS-LL1 Mapping-mode SPICE Optimal extraction |
In this cookbook, we demonstrate the data reduction strategies used
for ultradeep IRS spectroscopy. This page follows the IRS Best
Practices memo for the same observation, but we now include optimal
extraction in SPICE which was not previously available. The ultradeep
proof of concept data (PID=252) included observations in SL1, LL2, and
LL1. We use the LL1 data here. The target was a z=2.69 ULIRG. A total
of 12 hours on-source integration was performed, using mapping-mode to
place the target at 6 positions along the slit.
