[MITgcm-support] question about cube-sphere halos

[Benny Cheng]

Is it natural to expect zeroes at the corners of the haloes, ie:

Here is a sample output of XC(-2:2,-2:2)  ( with overlap OLX = 3)

0.00000000000000D+000   0.00000000000000D+000   0.00000000000000D+000  
314.896705843670  314.943947509892
0.00000000000000D+000   0.00000000000000D+000   0.00000000000000D+000  
314.955059294431  315.000000000000
0.00000000000000D+000   0.00000000000000D+000   0.00000000000000D+000  
315.000000000000  315.044940705569
314.858553626787        314.922753304848        314.976968595699       
315.023031404301  315.077246695152
314.828462712491        314.900664842638        314.967693942090       
315.032306057910  315.099335157362

so, XC(-2:0,-2:0)  is a always block of zeroes  ? same question for
other corners.
