... The generation of simulated sources whose physical properties are well understood is useful in assessing the functionality of point source analysis software. Qpsim is an IRAF/PROS task which will generate events from sources of given intensity, shape, and position and either overlay them on a flat background in a new QPOE file or inject them into an existing QPOE file. ... The simulated data can be a useful tool in calibrating point source analysis software. ...

... This command selects one subframe from the original frame and generates an artificial image identical to the primitive but with the quoted window added at given positions. If this window contains one stellar image, one is able to determine, through a new ROMAFOT session, the ability of the procedure to detect an object and the general reproducibility of the photometry. A catalogue, similar to that created by FIND/ROMAFOT , is generated by ADDSTAR/ROMAFOT . ...

... We performed photometry on both the original and deconvolved images of NGC 6352. ... Aperture photometry was performed on all stars identified in the deconvolved master frames with aperture radii of 4 and 5 pixels for the F555W and F785LP images respectively. ... Fig. 2 indicates that the scatter about the mean faint star sequence is much smaller for the aperture photometry of the deconvolved images than for the PSF fits to the original images. ...

... Circles are used to depict the source positions. ... A optional ID label can also be displayed alongside the circle, corresponding to the row num- ber of that source in the input source list. ... These circles are in fact DS9-type regions, which can be written out to a le for future use (for example, when running a later DS9 session) by setting withregionfile to true, and specifying the desired le name via the regionfile parameter. ... This is a text le containing region descriptions for each source...

... As stable VLT work horses during the past 8 years obviously the two FORSes have in many ways also been instrumental to the definition of the VLT queue observing paradigm which includes both systematic collection of calibration data, online and offline reduction pipelines. The original concept for the photometric calibration and the FORS imaging pipelines involved acquisition of simple twilight images which were used for flatfielding, and observation of Landolt photometric standards. ...

Jupiter's volcano-pocked moon Io has been found by NASA's Galileo spacecraft to have a giant iron core that takes up half its diameter, scientists report in today's issue of Science magazine. The spacecraft also has detected a large "hole" in Jupiter's magnetic field near Io, leading to speculation about whether Io possesses its own magnetic field. ... Galileo scientists also are trying to determine the cause of the hole they found in Jupiter's magnetic field when the spacecraft was closest to Io. ...
