The alternate table is derived from the delivered file SDC_ON_OFF_CMD_V0001.TAB. The delivered file, SDC_ON_OFF_CMD_V0001.TAB, was sorted by ascending channel, then by ascending time. So an on/off event on a lower channel will be earlier in the file than an earlier event on a higher channel. In this alternate table, the sort order is by ascending time, then ascending channel, so later events are later in the file and earlier events are earlier, regardless of on which channel they occur."
