. Each of the seven spectrometer boards operates on a 100 MHz clock. In addition each board receives a 1 Hz, 0.001% duty cycle (one 10?s pulse per second) signal; this 1PPS maintains synchronization with the telescope data feed. These two timing inputs from the observatory are converted into LVDS differential pairs and split by an octal driver on the timing board. The timing signals are connected to each of the spectrometer boards through RJ45 STP cables.
... This device holds a flashbulb, mirror, and photocell. ... As far as the ground observer is concerned, the clock on the ground is behaving normally the light travels up to the mirror and back and the clock ticks along. ... In other words, as far as the observer on the ground is concerned, the light in the moving clock travels a longer distance than the light in the clock on the ground. ... As far as the observer on the ground is concerned, the moving clock ticks more slowly. ...
... A clock is a tool for the time counting. The stable repeating processes are used in clocks. ... The first timepieces were sand glasses; in the 2nd thousand years B.C. there occured water clocks; the first mentions about mechanical timepieces related to the end of the 6th century; the modern mechanical timepieces are created by H. Huigens in 1657; in 70th years of the 20th century there were widespread the electronic quartz watches with numeric indication, for example on the liquid chips. ...

... Example images using the `cubehelix' colour scheme using AIPS . ... I have written up the implementation of a colour scheme -- called `cubehelix' -- which is intended to be perceived as increasing in intensity. ... There is no single `cubehelix', as there are several parameters that control this family of colour schemes: . ... This page gives several other colour wedges made with different parameters (along with the corresponding colour scheme files for use in DS9 or kvis , see Section 3.2 below). ...
... Bad Astronomy . ... Every few months, one of a series of questions comes up on the USENET group sci.astro involving tides, or the rotation of the Moon, or the recession of the Moon from the Earth. ... Why the Moon's rotation period is the same as the length of time it takes to orbit the Earth (same as number 1, but phrased differently). ... But when this happens, the time it takes for the Earth to rotate once will be slowed to exactly the same time it takes for the Moon to go around the Earth once! ...
