/*
* STRUCT: SE_Data_Table_Sub_Extent
*
* Specifies the bounds of the <Data Table> for which the user wants
* data returned. Used in the SE_GetDataTableData() function.
*
* A <Data Table> is an N-dimensional collection of data. This
* extents structure is an N-dimensional "area of interest" definition.
* It allows the user to specify starting and stopping indices of
* interest for each dimension of the <Data Table>. These indices
* are 0 based (traditional C array access).
*
* For example, consider a three dimensional <Data Table>, with
* dimensions of 100 by 100 by 5.
*
* To get all 50,000 values at once:
* axes_count = 3, axes_bounds[0].first_index=0,
* axes_bounds[1].first_index=0,
* axes_bounds[2].first_index=0,
* axes_bounds[0].last_index=99,
* axes_bounds[1].last_index=99,
* axes_bounds[2].last_index=4
*
* To treat it as 4 quadrants, 12,500 values each, the user could define:
* axes_count = 3, axes_bounds[0].first_index=0,
* axes_bounds[1].first_index=0,
* axes_bounds[2].first_index=0,
* axes_bounds[0].last_index=49,
* axes_bounds[1].last_index=49,
* axes_bounds[2].last_index=4
* axes_count = 3, axes_bounds[0].first_index=50,
* axes_bounds[1].first_index=0,
* axes_bounds[2].first_index=0,
* axes_bounds[0].last_index=99,
* axes_bounds[1].last_index=49,
* axes_bounds[2].last_index=4
* axes_count = 3, axes_bounds[0].first_index=0,
* axes_bounds[1].first_index=50,
* axes_bounds[2].first_index=0,
* axes_bounds[0].last_index=49,
* axes_bounds[1].last_index=99,
* axes_bounds[2].last_index=4
* axes_count = 3, axes_bounds[0].first_index=50,
* axes_bounds[1].first_index=50,
* axes_bounds[2].first_index=0,
* axes_bounds[0].last_index=99,
* axes_bounds[1].last_index=99,
* axes_bounds[2].last_index=4

Field Notes

of the following axes_bounds array
the array of index pairs representing each dimension
of the given <Data Table>.
