Binary file description
The
binary file’s first 2101 bytes is the header. The header is defined as:
-
The first byte is stating the number of ‘columns’ in the file (n columns)
- The next 100 bytes is defining the data-
type for each ‘column’ (only the first n values are set). Currently these
numbers are all 0x05, meaning 8-byte floating point (double)
- The remaining header bytes are 100 20-
byte strings with the header name for each ‘column’ (only the first n values
are set)
After the header follows the data measurement result values, stored as 8-byte floating point values (double) in groups
of n results.
