ABSTRACT:An all-sky map of IR-excess gas has been produced by subtracting the H I component from the IR brightness.
The large IR-excess residuals
that are spatially connected are used to define IR-excess clouds.
Also,
nearby molecular clouds at high Galactic latitude and clouds with local
heating sources or a larger dust-to-gas ratio than average are
identified.
The map and a catalog of 516 significant clouds are presented and
statistically analyzed.
