LIMISEG

The segment type of the last segment of a limit line is not returned since the type parameter de￿nes how the segments are drawn (connected) to the next segment. The last segment does not have a \next" segment. If there are 10 segments, the segment type for the ￿rst 9 is returned.

The three segment types are:

￿FLAT draws a zero-slope line between the beginning points of two segments, producing limit-line values equal in amplitude for all wavelengths between the two points.

￿SLOPE produces limit-line values of potentially varying amplitude for all wavelengths between the two points using linear interpolation.

￿POINT speci￿es a limit value for the beginning point only.

If the segment type is omitted, the type of the previous segment is used. Limit-line segments can be added during limit-line testing. The LIMISEG command works in conjunction with the following commands to de￿ne a limit line in the limit-line table:

1.LIMILINE clears the limit-line table, prepares it for data entry, and speci￿es the number of segments in the limit line.

2.LIMIHALF speci￿es whether the limit-line is an upper or lower limit-line.

3.LIMIREL determines whether the values of the limit line are absolute or are relative to the center-wavelength and reference level settings.
