... The particular variables it is concerned with are tick , which is the number of microseconds added to the system time during a clock interrupt, tickadj , which sets the slew rate and resolution used by the adjtime system call, and dosynctodr , which indicates to the kernels on some machines whether they should internally adjust the system clock to keep it in line with time-of-day clock or not. ... Set the kernel variable tickadj to an internally computed "optimal" value. -t tick . ...

... The task also issues a number of housekeeping related messages and values and also writes several keywords to the EXPOSURE extension (the information is usually CCD-dependent and it is thus important that it is kept and propagated through the event file processing chain). ...

RELATIVE SUNSPOT NUMBERS Description of Data from SGD Explanation of Data Reports: Relative Sunspot Numbers -- The relative sunspot number is an index of the activity of the entire visible disk of the Sun. ... The provisional daily Zurich relative sunspot numbers, Rz, were based upon observations made at Zurich and its two branch stations in Arosa and Locarno and communicated by M. Waldmeier of the Swiss Federal Observatory. ... This indicates the uncertainty above and below the predicted number. ...

... Let us first find out which way -- rise in spectral resolution with some loss in the S/N ratio or increase in the S/N ratio with a fixed spectral resolution -- is better for the purpose of reduction of equivalent width determination errors. ... N -- number of counts for 1 ? ... line equivalent width, . ... Thus if the spectral resolution is managed to be increased (i.e. to decrease )without loss in the number of counts falling at 1 ?, the equivalent width measurement error is then proportional to . ...

... Due to discontinuities in the line detections as well as in the calibration process, the dispersion relations computed by the row-by-row process could show row-to-row discontinuous variations. The command CALIBRATE/TWICE , provided that a sufficient number of calibration lines is available, can stabilize the solutions by performing a two-pass wavelength calibration which retains for the second pass only the lines that were consistently identified during the first pass. ...
