TWP/QCRAD/C1 - Reprocess: NIP calibration
DataStreams:twpqcrad1longC1.s1, twpqcrad1longC1.c1, twpqcrad1longC1.s2, twpqcrad1longC1.c2
Description:
Direct normal flux has incorrect calibration coefficient but can be fixed as described in 
instrument DQR D041106.1:

The tracker rotated and pulled the cable away from the NIP connector. In trying to 
discover
the problem with the NIP a new NIP was put in. When the problem turned out to be the 
cable,
the observers didn't put the former NIP back in. The NIP then in service was 31346E6
RS@45=8.1573 whereas the coefficients used were for the old NIP 299937E6 RS@45=7.8775
Suggestions:
