G29 explanation please

Hi I have been running on a Kossel G28 then G29.
All that I get after G29 is a heap of numbers but nothing about it compensating for a uneven bed like I have seen on others posts.
3.03 3.28 3.35 3.34 3.29 3.17 3.04 2.75 2.46
3.08 3.23 3.39 3.42 3.40 3.30 3.09 2.89 2.63
3.21 3.34 3.43 3.50 3.50 3.44 3.31 3.09 2.87
3.32 3.46 3.60 3.67 3.71 3.66 3.55 3.39 3.17
3.42 3.58 3.74 3.82 3.86 3.82 3.77 3.65 3.48
3.56 3.72 3.87 3.95 3.93 3.95 3.93 3.85 3.72
3.70 3.79 3.89 3.96 3.95 3.94 3.97 3.93 3.93
3.79 3.84 3.89 3.94 3.89 3.87 3.90 3.89 3.93
3.87 3.89 3.88 3.76 3.68 3.69 3.79 3.85 3.92

Is it compensating or just measuring?
Sorry I have no idea at the moment.
