# Difference between revisions of "HFI-Validation"

The overall internal validation of the frequency maps is seen thanks to several tests:

• difference between the PR2 and PR3 frequency maps,
• survey difference maps for the PR2 and the PR3 frequency maps,
• spectra of the PR2 and the PR3 data splits,

Frequency maps for the PR2 and the PR3 and their difference

This table shows the PR2 (2015) and PR3 (2017) maps and their differences in I, Q, and U. This table is complementary of Figure 11 of Planck-2020-A3[1] (see detailled explanations there).

Survey difference maps for the PR2 and the PR3 data

This table shows the PR2 (2015) and PR3 (2017) survey difference maps in I, Q, and U. This table is taken from Figure 12 of Planck-2020-A3[1] (see detailled explanations there).

Spectra of the PR2 and the PR3 data splits

This figure shows the $EE$ and $BB$ spectra of the 2015 and 2017 detset, half-mission and rings (for 2017 only) maps at 100, 143, 217, and 353\,GHz. The auto-spectra of the difference maps and the cross-spectra between the maps are shown. The sky fraction used here is 43\,\%. The bins are: bin=1 for $2\leq\ell<30$; bin=5 for $30\leq\ell<50$; bin=10 for $50\leq\ell<160$; bin=20 for $160\leq\ell<1000$; and bin=100 for $\ell>1000$. This figure is taken from Planck-2020-A3[1] (see detailled explanations there).
