... As with previous HST instruments, the FITS header keywords in STIS data files store important information characterizing the observations and telemetry received during the observations and describe the post-observation processing of your dataset. ...

... Charge Coupled Devices (CCD) are currently by far the most widely used type of detector in astronomy. ... After a brief introduction to the VLT Control System, the VLT CCD Detectors Control Software is presented. The VLT Control System is a distributed system consisting of a set of UNIX Workstations, dedicated to high level operations, such as coordination of sub-system activities and interface to the users, and VME-based Local Control Units (LCU), dedicated to the control of sub-systems hardware. ...

The Agile window provides complete control over the Agile high-speed photometer. ... All other parameters are specified as part of the command that starts an exposure sequence. ... To connect the filter wheel controller, issue this command in the command bar at the bottom of the Log window: agile connDev fw . ... To home the filter wheel controller, issue this command in the command bar at the bottom of the Log window: agile fwhome (there must be a filter wheel mounted in Agile for homing to succeed). ...

Strong support for the provision of a new Library, Archives and Historic Scientific Instruments Building was expressed by the Board of Governors at their annual meeting in March 2004. ... During 2004 the project was advanced largely by John Butler, who prepared a detailed application for external funding to support the proposal, which is intended to be submitted to the HLF in 2005. ...

... The Science Operation Department is composed of Astronomers, Telescope Instruments Operators(TIOs) and Data Handling Administrators(DHAs). ... Astronomers have proposed several methods to quantitatively measure the amount of turbulence above the telescope, which the most common ones is Differential Image Motion Monitor (DIMM). In optical testing, the Hartmann test is the common method to test the quality of optical components. ... Hartmann mask consists of 48 lenses. ...

... NOTE that this call also sets the state of the cal to the returned instrument. The and are obtained from respectively from the INSTRUME and DATE-OBS keywords of the dataset header. The is read from the RA_PNT , DEC_PNT and PA_PNT keywords (this is actually wrong, since the instrument attitude is what should be stored in these, not the spacecraft attitude). The boresight is then obtained for the exposure start time, and calculated by applying the boresight rotation to . ...

... The Miriad task uvgen can be used to simulate a variety of observing modes. ... Simulating a telescope approximately, let alone in some detail, requires a good many parameters. uvgen takes an appreciable number of parameters and input files to describe the telescope, correlator and source. Fortunately keyword and set-up files for some common situations exist ( e.g. simulating the ATCA and VLA). ... For example, to load typical parameters for the ATCA, use miriad% source $MIRCAT/uvgen.def.atca . ...

... The J, H and K bands are characterized by a bright background, such a background is mainly due to the emission of atmospheric lines and of thermal radiation. ... If the source cover a large fraction of the slit, spectra off-source must be observed to adequately sample the sky background. ... The on chip integration time (time spent in each position of the slit) must not exceed 40 seconds in J and H bands and 60 seconds in K band. ... We suggest a sequence of 10 for each elementary integration time. ...
