Subject:
PYE/AERI/M1 - Incorrect reporting of the hatch open status
DataStreams:pyeaerisummaryM1.b1
Description:
The polarity of the hatch controller was incorrect. The hatch was reported in an 
indeterminate position (red) when the controller was open and collecting data. Normally, when the 
hatch open metadata flag is red, the hatch is closed or partially closed and there is no 
sky data. However, because the polarity was reversed, the hatch flagged red when the 
hatch was open. The problem was resolved by reversing the polarity through software. The 
hatch flag now correctly reports the status of the hatch.
Suggestions: 
The user should disregard the hatch open metadata flag from March 8 through April 7, 

2005. The user can determine the status of the hatch from the spectral data. Data 
quality of data obtained when the hatch was open is not affected.
