This directory contains the following files:

MASTER_CRUISE_TABLE.XLS: This is an extended instrument operation table used 
during cruise and flyby operations of MASCS, showing details of VIRS and 
UVVS observations, times, and other information useful for quick reference. 
In orbit, the mission planning software SCIBOX takes over the function of 
this table. This file can be viewed using Microsoft Excel.

VIRS_CDR_EXCLUDED.TXT: This is a list of VIRS CDRs that are excluded from 
PDS delivery due to bad dark solutions. See VIRS_CDR_DS.CAT for more 
information.

VIRS_DDR_EXCLUDED.TXT: This is a list of VIRS DDRs that are excluded from 
PDS delivery due to
1) all footprints have shutter closed
2) all footprints are off planet
3) all footprints are in nightside shadow
4) bad dark solutions
See VIRS_DDR_DS.CAT for more information.


The following files describe missing packet errors observed in some MASCS 
VIRS data products.

VIRS_MISSING_PACKETS_R6.TXT: This file describes the investigation and 
resolution of the missing packet error described in the "Data Coverage and 
Quality" section of VIRS_CDR_DS.CAT. Included is a list of the EDRs (and 
thus also CDRs) missing packets for PDS release 6. 

VIRS_VIS_EDR_MISSING_PACKET_ANALYSIS_R6.XLS: This is a companion spreadsheet 
to the file above. It shows a detailed breakdown of the EDRs and exactly 
which packets are missing.

VIRS_VIS_MISSING_PACKETS_R*.TXT: These files list the incomplete VIRS VIS 
EDRs/CDRs for PDS releases, where '*' is the release #. The errors are 
described in the "Data Coverage and Quality" section of VIRS_DS.CAT.  

VIRS_NIR_MISSING_PACKETS_R*.TXT: These files list the incomplete VIRS NIR 
EDRs/CDRs for PDS releases, where '*' is the release #. The errors are 
described in the "Data Coverage and Quality" section of VIRS_DS.CAT.
