Cinrad2Record (All javadoc for netcdf-java version 4.6.22-SNAPSHOT)

java.lang.Object
- ucar.nc2.iosp.cinrad.Cinrad2Record

```
public class Cinrad2Record
extends java.lang.Object
```
This class reads one record (radial) in an CINRAD level II file. File must be uncompressed. Not handling messages yet, only data.
10/16/05: Now returns data as a byte, so use scale and offset. Adapted with permission from the Java Iras software developed by David Priegnitz at NSSL.
