5. Results

Below are the results of calculations for the standard PLANCK baseline and for the PLANCK LFI and HFI concepts separately.

Also the results for a revised PLANCK concept only including frequency bands 31.5, 53, 150, 217, 545 and 857 GHz, a concept based only on bolometric detectors with frequency bands 53, 90, 150, 217, 353, 545 and 857 GHz and results for the MAP concept are presented. For each mission concept the frequency bands used are listed in GHz and the resulting means and standard deviations for are given in units of K.

PLANCK Baseline:

Power-law 0.06 0.65

Two-temp. 0.51 1.08

PLANCK Bolometer:

Power-law -0.07 0.77

Two-temp. 0.44 0.97

PLANCK Revised:

Power-law -0.03 0.82

Two-temp. -0.24 1.13

HFI:

Power-law -0.01 0.93

Two-temp. 0.35 1.19

LFI:

Power-law -11.88 33.38

Two-temp. 1.96 36.37

With respect to the other parameters only those related to the dust emission can be stated since the synchrotron radiation and free-free emission are fitted as one power-law. The results for the dust show, that the spectral indecies and base-levels or optical depth, , are generally fitted to an accuracy of a few percent. The only exception to this is for the LFI and MAP configurations, where large deviations are observed. It should however also be noted that the combined synchrotron and free-free emission "fit'' done by the HFI configuration is not very well determined.

Our modelling shows, that MAP handles the two-temperature dust model equally well as the LFI concept but has some problems constraining the fit for the power-law dust model. Based on this a series of calculations are performed, where the dust is not fitted i.e. the term in Eq. (6) is omitted. This was done for both the MAP and the LFI concepts, with the following results:

LFI:

Power-law 7.35 32.96

Two-temp. 10.22 31.26

MAP:

Power-law 10.22 31.26

Two-temp. -0.01 12.75
