Observatories or missions, instruments, filters, possible observing modes, and the number of measurements with a specific instrument, in the present version of the Infrared Database.
| Mission | Instrument | Filters | Observing mode | Nobs |
|---|---|---|---|---|
| AKARI | IRC-NIR | N4 | IRC02 | 1 |
| IRC-MIR-S | S7, S9W, S11 | Survey, IRC02, IRC11 | 6955 | |
| IRC-MIR-L | L15, L18W, L24 | Survey, IRC02, IRC51 | 13 824 | |
| HSO | PACS | Blue,green,red | Chop-nod, scan map | 1852 |
| MSX | MSX_A,MSX_C,MSX_D,MSX_E | Survey | 901 | |
| IRAS | IRAS12,IRAS25,IRAS60,IRAS100 | Survey | 25 064 | |
| WISE | W3,W4 | Survey | 121 383 | |
Notes. Instruments on low-Earth orbits, such as AKARI, MSX and IRAS are referred to as geocentric (JPL code “500@399”), and we used the JPL code “500@-163” for WISE and “500@-486” for Herschel.
