GATES* 1D <1D-gate-map-name>[<xrange>]
(<low-limit> <high-limit>)1 (<low-limit> <high-limit>)2 ... (<low-limit> <high-limit>)ngates
where <xrange> is specified as:
<lower-limit>:<upper-limit>
or
<range>
where <lower-limit> would be set to zero and <upper-limit> would be equal to <range> minus 1.

defines a set of 1D gates BAND1 within the limits 0 to 511 inclusive which contains 3 gate definitions: gate 1 is defined as channels 123, 124, 125, 126; gate 2 as channels 245, 246, 247,..., 254, 255, 256; and gate 3 as channels 257, 258, 259, 260,..., 268, 269, 270 because gate 3 overlaps gate 2.GATES 1D BAND1[0:511] (123 126) (245 259) (257 270)
