Best-fit estimates for the global scaling parameter, aα, for various calibration methods.
| Planck map | Global fit | Mean of 30 | Median of 30 | Global fit | Mean of 30 | Median of 30 | Planck |
|---|---|---|---|---|---|---|---|
| (type and line) | (with offset) | (with offset) | (with offset) | (no offset) | (no offset) | (no offset) | (estimate) |
| TYPE 1 J =1 → 0 | 1.12 | 1.09 ± 0.07 | 1.08 | 1.21 | 1.19 ± 0.09 | 1.20 | 1.11/1.16 |
| TYPE 1 J = 2 → 1 | 0.61 | 0.60 ± 0.06 | 0.60 | 0.60 | 0.59 ± 0.06 | 0.58 | |
| TYPE 1 J = 3 → 2 | 0.21 | 0.23 ± 0.06 | 0.22 | 0.19 | 0.20 ± 0.04 | 0.19 | |
| TYPE 2 J =1 → 0 | 1.26 | 1.26 ± 0.07 | 1.25 | 1.24 | 1.24 ± 0.08 | 1 . 23 | 1.2 |
| TYPE 2 J = 2 → 1 | 0.61 | 0. 61 ± 0. 06 | 0.62 | 0.67 | 0.67 ± 0.09 | 0.66 |
Notes. Statistical errors for the global fits are not reported, as they are very small (on the order of 10−4 to 10−3) and not representative of actual uncertainties given the variation of the calibration coefficients over the sky. The two Planck values reported for TYPE 1 J = 1 → 0 are from a model with 13CO/12CO ≃ 0.2 and a 0.53 × 13CO contamination estimate in the TYPE 1 J = 1 → 0 map, and from a fit performed by the Planck team over selected sky regions.
