The dataset is continuum maps at 155 microns observed by the Far-Infrared Line Mapper (FILM), a focal-plane instrument of the Infrared Telescope in Space (IRTS).

This contains 1 map and supplemental data per observation region. The information of the scanpath and observation regions is described in Data list and Scan-Path. NS37 and SS53 are identical to NS01 and SS01, respectively. They were created for cross-check purpose and were not necesserrily downloaded.

All the quick-look images of each observation are listed on this page.

Caveat

Some problems are found in the ver. 2.1 data for the following 7 scan regions: North Scan (NS) : 18, 20, 21, 29, and South Scan (SS) : 18, 21, 44. There are pixels with incorrect values in these datasets. Please use this ver.2.0 data instead for these regions.
