FIRAS Small Source Spectral Energy Distributions
This interactive service permits browsing of the FIRAS data for preliminary investigations of localized sources. Detailed information about the FIRAS instrument, its operation, calibration, and the FIRAS data products can be found in the FIRAS Explanatory Supplement. Given an on-source position and offsets for reference positions, this service displays the on-source, average off-source, and difference spectra for the frequency range 70-2880 GHz with 21 GHz resolution. A brief explanation of this form is available.
Enter the coordinates and select the system and epoch of the position of interest. For the reference positions, specify the angular offsets, the directions, and the system. The integral flux will be estimated for the wavelength integration range specified.
