CALIB Directory Contents:                                                     
                                                                              
The CALIB directory contains instrument performance reports and engineering   
telemetry data tables relative to data in the current Data Set. It is         
organized into subdirectories named according to the same scheme used for     
subdirectories in the DATA directory.                                         
                                                                              
The reports themselves are in the form of detached-label Spreadsheet Data     
Objects, called logs. Each row in a log lists the value of a number of        
parameters identifying a data take, describing the quality of the data, and   
some geometric information provided for ease of reference. The log themselves 
are contained in files named LOG_ddd_nnnn.CSV, where:                         
                                                                              
- ddd is an identification of the data set they belong to,                    
                                                                              
- nnnn is the number of the orbit for which a log is provided.                
                                                                              
For example, the instrument performance report for orbit 1886 in the          
EXPERIMENT DATA RECORD Data Set is contained in the CALIB subdirectory        
EDR0188X and is named LOG_EDR_1886.CSV. The file containing the corresponding 
detached label is called LOG_EDR_1886.LBL                                     
                                                                              
In the CALIB directory there are also files reporting engineering parameters  
of the instrument, called MARSIS_APID20_C_xxxx.CSV, MARSIS_APID20_T_xxxx.CSV, 
MARSIS_APID20_V_xxxx.CSV files where xxxx is the number of the orbit. These   
spreadsheets report respectively  currents, temperatures and voltages measured
within the instrument during a single orbit. The files containing the         
corresponding detached label MARSIS_APID20_C_xxxx.LBL,                        
MARSIS_APID20_T_xxxx.LBL, MARSIS_APID20_V_xxxx.LBL
