**drwls**, Tuesday, December 21, 2010 at 1:28amWhat is a bunch crossing? Bunch of what?

What are mb units? Millbarnes?

cm/s is not a unit of luminosity

What is T? What are its units?

this is jibberish

**Dr Russ**, Tuesday, December 21, 2010 at 5:52amTrying to sort out the units.

20 mb = 20 millibarns (mbarn)?

the luminosity is presumably cm2 s^-1

because by definition

event rate = luminosity * cross section

Not sure of units of T ns?
