Identification of marginal data sets 



Although problems did exist with some data sets, the majority of data 

 collected are accurate and useful. During the first week, data from the OBS 

 located 9 cm from the bed were corrupt, because the face of the sensor was 

 partially blocked by the mounting apparatus. This problem only occurred
