The Radiometric Calibration of SOHO

Results from the Golf Instrument on Soho

An 800 day series of GOLF velocity data, with uniquely high continuity and stability, ooers the best ever signal to noise ratio obtained in global Sun observations. Following meticulous eeorts to provide reliable calibration, these data have been used for measurements of frequencies, line-widths and power in the p-modes, which are used for inversion to give the internal sound speed, for compari...

We argue that states will be able to prevail in improving their allotment of a good or in convincing an opponent to back down, and have shorter crises, if their opponents have greater expected costs of crisis.
