PYE/MPL/M1 - wrong temperature calibration

Wrong calibration coefficients were applied to the temperature values.  These are 
engineering housekeeping data only.  The scientifically relevant measurements were unaffected.

PYE/AERI/M1 - Incorrect reporting of the hatch open status

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.

PYE/MFRSR/M1 - Misalignment/Shading Problem

Diffuse and direct normal data were corrupted because the mechanical band motor latitude 
was incorrect at installation.  Corrected 5/20.

Around solar noon, data look okay but rest of data are poor and should not be used.

PYE/MWRP/M1 - Bias in Ground Relative Humidity Measurement

On June 17 2005, the MWRP was re-installed at PYE after the Super Blower was replaced by 
the old style dew blower. The relative humidity ground sensor in the dew blower is not as 
accurate. This resulted in a negative relative humidity bias of about 5.9 %. In other 
words the MWRP sensor was underestimating the relative humidity. The bias was determined by 
comparing MWRP measurements with SMET and radiosonde measurements. The MP.cfg file for 
the MWRP was changed to reflect this bias on 09/02/2005 and will take effect on 09/03/2005

PYE/MPL/M1 - Erroneous temperatures

The temperature readings for the laser, detector, and instrument are erroneous.  Incorrect 
calibration factors; data should not be used.  This time period is prior to the official 
start of the PYE deployment.
