Intercalibration of SUMER and CDS on SOHO III SUMER and CDS-GIS

Applied Optics, 2003
Simultaneous observation of the same solar sources with different instruments is one way to test prelaunch radiometric calibrations and to detect changes in responsivity with time of extreme-ultraviolet instruments in space. Here we present the results of intercalibration of the SUMER (Solar Ultraviolet Measurements of Emitted Radiation) spectrometer ...

The sixty system of sumer

Archive for History of Exact Sciences, 1965
The most familiar fact about the Sumerian system of numeration is that it was based on the number sixty, very much as ours is based on the number ten: thus just as our words twenty and thirty etymologically signify 2X10 and 3 X 10, so did the Sumerian words gesh-min and gesh-esh signify 60 X 2 and 60 X }.

Spectroscopic diagnostics for CDS and SUMER

Space Science Reviews, 1994
The CDS and SUMER instruments will make extensive use of spectroscopic diagnostics to determine the physical parameters of the solar transition region and corona. A great deal of effort is going into the development of these techniques to ensure that they are accurate.
