  We use data from Cassini's Composite Infrared Spectrometer CIRS to map Mimas'
surface temperatures and its thermophysical properties. This provides a
dramatic improvement on the work in Howett et al. (2011), where the values were
determined at only two regions on Mimas (one inside, and another outside of the
anomalous region). We use all spatially-resolved scans made by CIRS' focal
plane 3 (FP3, 600 to 1100 cm-1) of Mimas' surface, which are largely daytime
observations but do include one nighttime one. The resulting temperature maps
confirm the presence and location of Mimas' previously discovered thermally
anomalous region. No other thermally anomalous regions were discovered,
although we note that the surface coverage is incomplete on Mimas' leading and
anti-Saturn hemisphere. The thermal inertia map confirms that the anomalous
region has a notably higher thermal inertia than its surroundings: 98 +/- 42 J
m-2 K-1 s-1/2 inside of the anomaly, compared to 34 +/- 32 J m-2 K-1 s-1/2
outside. The albedo inside and outside of the anomalous region agrees within
their uncertainty: 0.45+/-0.08 inside compared to 0.41 +/- 0.07 outside the
anomaly. Interestingly the albedo appears brighter inside the anomaly region,
which may not be surprising given this region does appear brighter at some UV
wavelengths (0.338 microns, see Schenk et al., 2011). However, this result
should be treated with caution because, as previously stated, statistically the
albedo of these two regions is the same when their uncertainties are
considered. These thermal inertia and albedo values determined here are
consistent with those found by Howett et al. (2011), who determined the thermal
inertia inside the anomaly to be 66 +/- 23 J m-2 K-1 s-1/2 and less than 16 J
m-2 K-1 s-1/2 outside, with albedos that varied from 0.49 to 0.70.
