XMM-Newton Science Analysis System . ... CORR_RATE - The count rate after the following corrections have been applied; . 1) A further point-spread function correction may be applied, to extrapolate the counts from 12 to 35 pixels (presently only done for UV observations) 2) Correction for dead-time. 3) Correction for the OM sensitivity-degradation. A key-word TDS_CORR is added to the table to record the correction value. ... XMM-Newton SOC/SSC -- 2008-07-02 ...

... Driver ID: IRIG-AUDIO . ... This driver supports the Inter-Range Instrumentation Group standard time-distribution signal IRIG-B using the audio codec native to the Sun SPARCstation. ... The driver gadget uses a modified BSD audio driver for the Sun SPARCstation which provides a timestamp, raw binary timecode, status byte and decoded ASCII timecode. ... The 100 elements of the IRIG-B timecode are numbered from 0 through 99. ... This driver presently does not use the CF elements. ...

Geomagnetic disturbances can be monitored by ground-based magnetic observatories recording the three magnetic field components. The global Kp index is obtained as the mean value of the disturbance levels in the two horizontal field components, observed at 13 selected, subauroral stations . ... Geomagnetic activity is the occurrence of K variations. ... But K still remains a local index, describing disturbances in the vicinity of each observatory. ...
