Mean: 310.392
Variance: 17786.5

Statwt Summary

In the tables and plots below, the weight properties are shown in the "antenna-based" scale: we first derive the optimized solutions to Wt_bl_ij=Wt_i*Wt_j for individual integrations, where Wt_bl_ij is the "baseline" weight (i.e., the MS WEIGHT column) and Wt_i/Wt_j is the "antenna-based" weight; then we compute and present the statistical properties of the latter values after slicing them along different data axes (antenna, spw, scan). Note that there is a square scale difference between the baseline weights and the antenna-based weights.

The color background present in some table cells highlights spectral windows with a statistical property signficantly deviated from its median over all of the relevant group (spw, scan, antenna):

For values above the median, shades of red are used:

3σ≤dev<4σ

;

4σ≤dev<5σ

;

5σ≤dev<6σ

;

6σ≤dev,

where σ is defined as 1.4826*MAD.

For values below the median, shades of blue are used:

3σ≤dev<4σ

;

4σ≤dev<5σ

;

5σ≤dev<6σ

;

6σ≤dev,

where σ is defined as 1.4826*MAD.
