Effective frequencies and Gaussian beam widths assumed for extraction per channel.

FWHM νeff
Channel [arcmin] [GHz]

100 .......... 9.66 103.42
1430 .......... 7.22 144.90
2170 .......... 4.90 222.60
3530 .......... 4.92 355.22
5450 .......... 4.67 528.40
8570 .......... 4.22 776.58

Notes. The beam widths are the mean full-width-at-half-maximum, in arcmin, of the Gaussian fits to the per-pixel effective beams estimated by the FEBeCoP algorithm (Mitra et al. 2011).The effective frequencies νeff, shown in GHz, encapsulate band-pass effects in each channel (Planck Collaboration VIII 2016).

Current usage metrics show cumulative count of Article Views (full-text article views including HTML views, PDF and ePub downloads, according to the available data) and Abstracts Views on Vision4Press platform.

Data correspond to usage on the plateform after 2015. The current usage metrics is available 48-96 hours after online publication and is updated daily on week days.

Initial download of the metrics may take a while.
