Subject:
MAG/TSI/M1 - Ship mast in field-of-view
DataStreams:magtsiskycoverM1.b1
Description:
The mast of Horizon Spirit cargo ship was in the field-of-view of the TSI and contributed 
to the calculated fractional sky cover amount (i.e. the ship's mast was interpreted as a 
cloud). This effect is most apparent during clear sky periods and negligible during 
overcast periods.

An algorithm will be developed to remove the contribution of the ship's mast to the 
fractional sky cover determination.
