The ASM Picture Book.

The ASM Site Layout at Paranal showing the Meteorological Mast, the DIMM Telescope Tower and the ASM Control Room. The grid size is (dUxdV)=8x8 meters. In the Telescope area local coordinate system, UT1 is centered at (U,V)=(-16,-16) and the DIMM tower is distant of 200m to the North-East, centered at (U,V)=(146.10,102.06) The tower is oriented with one axis parallel to the North-South direction (the geographical North makes a positive angle of 19.55 degree with respect to the V (vertical) axis)
