Holography map Nov 5 1999 large scale errors
Large scale surface errors (May 18 1999)
Image of the large scale errors of the JCMT dish as measured on May 18 1999. The rms
of the large scale surface errors is 7.2 microns.
Note however that the above map does not include
systematic errors from the holography system itself, or from imperfections of the
panels such as surface roughness and scalloping..
