The Herschel Gould Belt Survey images follow the following naming convention:

[field]-[band].fits

where "field" is the name of the field, and "band" is the Herschel band wavelength 
in microns. 

[field]-[band]_cut.fits

are cutouts of larger maps that have not yet been released.

Some fields have -C, -N, -S suffixes, for Central, North, or South regions.
The Pipe Nebula includes pointings of the B59 and B68 regions.


The column density and temperature maps have names:

[field]_column_density_map.fits
or
[field]_coldens.fits

and

[field]_dust_temperature_map.fits
or
[field]_Tdust.fits

Additional figures and catalogs are available for some fields.
