What's the meaning of these defines?

#define CHAN_UTIL_HDR_LONG (202 * CHAN_UTIL_PER_USEC)
#define CHAN_UTIL_HDR_SHORT (40 * CHAN_UTIL_PER_USEC)

I can't figure out what the values 202 and 40 are.

And probably related, what does it mean for a bitrate to be an "ERP
rate"? Does that just mean it's an OFDM bitrate?
