1D gates

A 1D gate-map consists of one or more pairs of values. The range of values in between each pair (inclusive) defines a single gate. Within a set of gates successive gates in a 1D set have precedence over earlier ones. This means that in the commands section if a value would pass more than one gate out of a set then the latest such gate defined would be the one passed.


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.


*or GATEMAP for compatibility with earlier versions.

eg.

GATES  1D  BAND1[0:511]
(123 126)  (245 259)  (257 270)
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.
