... The process of proposing for Hubble Space Telescope observing time has been revised, to make it simpler for proposers. We describe the simple, flexible, and robust prototype system created to handle proposal submission. ... Proposing for Hubble Space Telescope ( HST ) observing time proceeds in two phases: the scientific merits of the proposal are considered in Phase I; only accepted proposals enter Phase II, where the observations are described in complete detail. ...

Next: Visibility Processing Up: Primary Beams and Mosaicing Previous: Mosaicing . ... Pointing grid pattern: In a mosaic experiment, you observe a number of pointings - possibly a few to several hundred, depending on the size of the source of interest. ... For a well-illuminated dish, this spacing corresponds roughly to half-power point spacing between field centres. ... Field Naming Convention: When preparing the observe files for an ATCA mosaic experiment, you will create a `mosaic file'. ...

Next: Stars Up: File Formats Required Previous: File Formats Required . ... It is not so obvious that planning and reducing photometric observations also require information about the telescope used. ... This information is needed both for planning observations and reducing data. ... Many instrumental details influence the methods that must be used in reducing photometric observations, because the data-reduction process must accurately model the instrument's performance. ... Instrumental data . ...

... 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. ...

You re in good company: This question also stumped the physicists who first tried to understand nuclear fusion in stars. In a star s core, all atomic nuclei have been separated from their electrons, so each hydrogen atom is really just a proton and thus holds a positive charge. ...

A Terra Hunting Experiment at the INT Rationale To detect smaller mass planets (down to 1Mе) using the radial velocity technique, we need to be able to retrieve a signal in the limit of stellar variability noise. ... Such an observing program is not feasible with a non-dedicated telescope. To address this, we are proposing a "Terra Hunting Experiment" to be performed using a close-copy of the HARPS spectrograph installed on the 2.5m Isaac Newton Telescope (INT) in La Palma. ...
