compare_cond

 COMPARE_COND -  Diagnostics plots to compare CTD and samples conductivity values.

 CTD Calibration toolbox.

 USAGE:
 compare_cond(cruiseid);

INPUT: cruiseid: Cruise identification name.
   
 OUTPUT: A series of plots to compare CTD and bottle samples conductivity values 
          
 DESCRIPTION: This function uses the summary conductivity calibration file created by  
 make_cond_sum and do a series of diagnostics plots to compare CTD and
 bottle samples conductivity values to evaluate the quality of the data
 that we are coleecting, as well, any potential problems with
 niskin/sample bottles or sensors.
