1. Introduction
The raw ACF data is the primary (first order) data product from the SuperDARN radars. Listed below is the C data structure struct RawData used to store the ACF data.
2. Array Limits
The array limits are defined as macros in the header superdarn/limit.h.
#define LAG_SIZE 96
#define MAX_RANGE 300

3. struct RawData
The ACF data structure is defined in the header superdarn/rawdata.h.
struct RawData {
struct {
int major; /* major revision */
int minor; /* minor revision */
} revision;
float thr; /* lag-zero power threshold level */
float pwr0[MAX_RANGE]; /* lag-zero powers
float acfd[MAX_RANGE][LAG_SIZE][2]; /* ACF data */
float xcfd[MAX_RANGE][LAG_SIZE][2]; /* XCF data */
};
