Amanda, pay close attention to the meaning of the index returned by the
where function. In this call, you will have the index where the value is
gt 1000 in your column of interest. arr[1440,*] is a 1D array. Then,
with these index, you are applying them to arr, which is a 2D array.
Therefore, you end up writing the mean value to the first LINE of your
array...
