9Of the 144,781 floats (481 x 301) in the C{lat_corr_} and C{lon_corr_} columns 

10of the C{rdcorr2018.txt} grid file only 55,139 respectively 55,348 are non-zero 

11between indices [8598:93827] respectively [8598:93830] (and 89,642 respectively 

1289,433 are zero).

14As a result, the first 28 and the last 169 matrix rows (in total 197 rows or 41% 

15of 481) are representable by the same 301-array of single-precision zeros. There 

16are other runs of zeros, but none amount to 301 or more.
