Linear coefficients, αj, of the templates used to clean individual frequency maps with SEVEM for temperature.

Notes. The 353–143 template has been produced at the same resolution as the 70 GHz frequency channel, while the 857 GHz map has been convolved with the 545 GHz beam. The rest of the templates are constructed such that the first map in the subtraction is convolved with the beam of the second map and vice versa.
