... Radio astronomy . ... This is impractical so, instead, we synthesise such a telescope by building an array of antennas. ... To obtain very high resolution, we use a technique known as Very Long Baseline Interferometry (VLBI) where we combine signals from the ATNF antennas together with other antennas in Australia, to form the Australian VLBI array, which can synthesise a telescope up to 3000 km in diameter. The resolution of this array exceeds even that of the Hubble Space Telescope. ...

... The FOC suffers from various types of background, the most important of which are thermal electrons, Cerenkov radiation from high energy particles, geocoronal emission lines, zodiacal light, and light scattered within HST from the bright Earth or Moon. ... From on-orbit measurements using the f /96 camera, the former background has been found to vary with solar zenith distance (ZD); see Sections 6.4, 6.5, and 7.0 of the FOC Instrument Handbook , version 7.0, for more details. ...

Next: CCD Operation Up: Charge Coupled Devices (CCDs) Previous: Charge Coupled Devices (CCDs) . ... However it is only now that a number of important X-ray astronomical applications of CCDs have reached critical development stages, so that this is an appropriate time to review the application of space-borne CCD instruments to cosmic X-ray astronomy, and highlight the particular concerns which are being addressed for X-ray instruments, as distinct from optical applications. ...

11. Optimization of spectroscopic observations
... 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 . ...
