Can I change glow values based on values in a CSV file?

There's many thousands of values, but here's a snippet:

Frame,Luminance,Cut
0,65.07,X
6,64.38,
12,63.55,
18,62.07,
24,61.25,
30,60.42,
36,61.15,
42,61.96,
48,62.44,X
54,62.94,
60,63.46,
66,64.56,
72,65.42,

And at the end of the CSV is:

Top 10 Brightest Frames
Rank,Frame,Luminance
1,4956,72.05
2,6354,71.95
3,4950,71.93
4,9096,71.92
5,4962,71.66
6,6384,71.65
7,9102,71.62
8,6390,71.61
9,18150,71.59
10,9126,71.45

Top 10 Darkest Frames
Rank,Frame,Luminance
1,36090,53.20
2,36096,54.48
3,29262,55.44
4,36102,55.53
5,48714,55.92
6,13722,56.10
7,51234,56.18
8,50940,56.25
9,45720,56.26
10,29256,56.2

The top 10 values are so I can go to the lightest and darkest frames to sample what the glow intensity looks like at it's most extreme values.
