These directories contain plots of the Tololo and Pachon DIMM and MASS 
measurements for each night.

In 2009, one of the ex-TMT MASS DIMMs was deployed on Tololo for routine use. 
This is T3. For 2009 and the beginning of 2010, there are thus plots for 
both T3 and the Tololo DIMM. In early 2010, the Tololo DIMM was decommissioned 
and only T3 is currently running.

MASS profile plots are not currently available, but will be soon. All the MASS 
data is being archived. 

On the seeing plots, there is a MASS free seeing curve. This is labeled "mass
corrected seeing." Corrected refers to the fact that the data have been post
processed to correct for strong scintillation. Free seeing includes 
contributions from all the mass layers, but excludes the ground layer (roughly
above 0.5 km). Thus the difference between the DIMM seeing and mass seeing is
a robust indication of the ground layer seeing.
