SGP/RL/C1 - No liquid water data in RLPROFmerge

From 20060906 to 20080304 the liquid water channel (LWC) was disabled due to the removal 
of its photomultiplier tube (PMT).  During this period the signals recorded in the 
sgprlC1.a0 files for the LWC contain invalid data, and so the decision was made not have the 
rlprof_merge vap process the LWC data. As a result, the sgprlprofmerge1turnC1.c0.*.cdf files 
contain NO LWC fields (variables or attributes) during this period.
   
Do not attempt to read any fields (variables or attributes) associated with the liquid 
water channel in the sgprlprofmerge1turnC1.c0.*.cdf files between the dates of 20060906 
through 20080304.
