The sheet will be called ‘<strong>AvaSoft</strong> Data’, the columns contain the following data:<br />
Column A contains a data/time value, formatted as ‘dd:mm:yyyy hh:mm:ss’.<br />
This is a floating point value, in which the integer part is the day number, starting at January 1,<br />
1900 with day 1. The fractional part represents a decimal time value, where 0.5 is 12:00 h. noon<br />
and 0.75 is 18:00 h.<br />
This way, differences in date/time can be readily calculated by subtracting values, which would be<br />
much more difficult if this was a text representation.<br />
Column B contains a time value, representing the elapsed milliseconds since midnight. This value<br />
does not have a one millisecond resolution. Remember that Windows is not a real-time operating<br />
system. It can, however, be used as a reasonably accurate indicator of the time that passes<br />
between scans.<br />
Columns C through J contain the 8 different History Channel values. For unselected History<br />
Channels, a value of 0 will be entered in the sheet.<br />
If you select ‘View Spectrum’ in your choice of History Channels, the sheet will be formatted<br />
vertically. As Excel only offers 256 columns per sheet, we need to write a spectrum (which can hold<br />
more than 2000 pixels) in a column instead of a row, and add more columns as time passes.<br />
