====== The Infrared Telescope in Space (IRTS) ======
The IRTS is the first Japanese orbiting mission for infrared astronomy.
The IRTS was equipped with a 15-cm cooled telescope and four scientific instruments :
- the Near-InfraRed Spectrometer (NIRS; ''1.4-4.0 µm'')
- the Mid-InfraRed Spectrometer (MIRS; ''4.5-11.7 µm'')
- the Far-Infrared Line Mapper (FILM; ''145, 155, 158, 160 µm'')
- the Far-InfraRed Photometer (FIRP; ''150, 250, 400, 700 µm'')
The angular resolution of the FIRP images is 0.5 deg and units are ''W/m2/sr/Hz''.\\
