Subject:
SGP/XSAPR/I5 - Data Quality Impacted
DataStreams:sgpxsaprppiI5.00, sgpxsaprvptI5.00, sgpxsaprhsrhiI5.00
Description:
The XSAPR came back up for a short period of time.  Radar was not properly calibrated and 
suffered from other problems noted below.

Differential reflectivity values were all greater than 4 dB
Correlation Coefficient values were all below acceptable levels (most below 0.8)
PhiDp values were noisy and do not appear to increase with range
Specific differential reflectivity is incorrectly calculated
Elevated background noise in the reflectivity
Suggestions: 
Use with caution
