MESSENGER MASCS UVVS and VIRS Housekeeping Experiment Data Record (MASCHK)

MASCHK – UVVS and VIRS Housekeeping Experiment Data Record

Instrument: MESSENGER Mercury Atmospheric and Surface Composition Spectrometer

PDS Data Set ID:

For more information about UVVS Housekeeping products, see the UVVS EDR Product SIS.

For more information about VIRS Housekeeping products, see the VIRS EDR Product SIS.

The Mercury Atmospheric and Surface Composition Spectrometer (MASCS) UVVS and VIRS Housekeeping Experiment Data Record (MASCHK) data product is common to both the UVVS and VIRS subsystems. The product contains MASCS Housekeeping data. Voltage, current, and temperature parameters are converted from raw DN counts into engineering data values.

MASCS MASCHK products are named according to the following file naming convention:

MASCS_HK_yyddd.DAT (with detached PDS label)

where:

yy = 2-digit year in UTC time converted from the first Mission Elapsed Time (MET) in the EDR

ddd = 3-digit day of year in UTC converted from the first MET in the EDR

In ODE, MASCHK products appear under the following product IDs:

MASCS_HK_YYDDD_DAT
