IDL Data Structure for raw I and Q data

Summary

A description of the IDL data structure used to store raw I and Q data.

Description

The raw ACF data is the lowest level (zero order) data product from the SuperDARN radars. Within IDL a structure is used to store the I and Q data.

Constants

A constant is used to define array limits

MAXNAVE=300

Raw I and Q data structure IQData

       revision: {rlstr, major: 0L, $        ; major revision
