Title: | Effect of bandpass on dipole calibration | Authors: | MARIS, Michele VASSALLO, Thomas |
Issue Date: | 2015 | Number: | PL-LFI-OAT-TN-095 | Abstract: | The gain G in Planck is estimated on an pointing period basis by comparing the observed dipole amplitude with the expected dipole amplitude [AD-1]. So the ultimate accuracy in calibration is connected to the ability of the DPC to properly simulate the signal of the Cosmological Dipole. This in turn depends on the ability of DPC to properly calculate the proper E4Pi convolution parameters. The E4Pi parameters are in turn computed from a GRASP model of beams and the QUCS model of bandpass. The bandpass model is affected by unknown level of uncertainties of which we want to estimate the impact on calibration and dipole residuals. Here we assumed a model of systematic uncertainty in banpasses and we propagate its effect on the maps through E4Pi convolution parameters. | URI: | http://hdl.handle.net/20.500.12386/33656 | Fulltext: | open |
