  The FIBRE-pac (FMOS image-based reduction package) is an IRAF-based reduction
tool for the fiber multiple-object spectrograph (FMOS) of the Subaru telescope.
To reduce FMOS images, a number of special techniques are necessary because
each image contains about 200 separate spectra with airglow emission lines
variable in spatial and time domains, and with complicated throughput patterns
for the airglow masks. In spite of these features, almost all of the reduction
processes except for a few steps are carried out automatically by scripts in
text format making it easy to check the commands step by step. Wavelength- and
flux-calibrated images together with their noise maps are obtained using this
reduction package.
