PowerBin: Fast Adaptive Data Binning with Centroidal Power Diagrams
Adaptive binning is a crucial step in the analysis of large astronomical datasets, such as those from integral-field spectroscopy, to ensure a sufficient signal-to-noise ratio (S/N) for reliable model fitting. However, the widely used Voronoi-binning method and its variants suffer from two key limitations: they scale poorly with data size, often as O(N^2), creating a computational bottleneck for modern surveys, and they can produce undesirable non-convex or disconnected bins. I introduce PowerB…

Do I have any PowerBi user in the thread?
I have 3 columns and I want to make every second row in the third column into a separate column. A list of 100 rows should become a list of 50 rows in 4 columns (every second row has moved to a new column). I have tried so many ways to pivot that my head is spinning (but have not succeded), I have been searching YT and the internet without any luck [the problem is that in all videos the rows are stacked in a single colum, not a table].
How…
