and find the percentage of them.
Is there a way to get the counts correctly ? that is my botheration now !!
with best regards,

The difference appears
to be that the boolean selection pulls out all data values
<= 0.5 whe

Good hint -- a masked array keeps the "junk" values in the main array.
What "abs" are you using -- it may not be mask-aware. ( you want a
numpy abs anyway)
Also -- I'm not sure I know what happens
Seems to be related to the masked values:
print r2010[:3,:3]
[[-- -- --]
[-- -- --]
[-- -- --]]
print abs(r2010)[:3,:3]
[[-- -- --]
[-- -- --]
[-- -- --]]
print r2010[ r2010[:3,:3] <0 ]
[-- -- -- -- -- -- -- -- --]
print r2010[ abs(r2010)[:3,:3] < 0]
