cat-kan(E3*) position (kb)	Rate of recombinational repair with amp-kan(K138*) at position (kb):
	–300′	–150′	+150	+300	+450	+600	+750	+1200	+1650	+2100
−150			3.0	2.6	11.5	4.6	9.5	3.0	1.8	4.0
−300		4.0	2.6	1.8	4.6	4.6	3.5	1.8	3.0	4.0

^aAll values are shown as times 10⁻⁶ per cell per generation. See Table S2 for 95% confidence intervals.

^bThe insertion site of the kan cassette in the Salmonella chromosome in kilobases relative to oriC. Negative values correspond to locations on the left replichore, and positive values correspond to locations on the right replichore. All recombination cassettes are inserted in the direction of replication unless indicated otherwise by a prime symbol after the location number.
