... To be read in conjunction with Section 4.11 of the WFPC2 Instrument Handbook , -Version 4.0. ... 1 The second study found evidence that CTE loss for faint stars has increased with time (Whitmore, 1998). The primary observational consequence of CTE loss is that a point source at the top of the chip appears to be fainter than if observed at the bottom of the chip, due to the loss of electrons as the star is read out down the chip (see Figure 1 ). ...

First of all FM-3 M1 data are used, if they are absent, MIF data used and if data of both magnetometer are absent, FM-3 M2 data presented. ...

... Right: Corresponding scan tracks for the same date ( red ) and previous dates ( blue ), which cover about 2/3 of the map area (the field was completed on June 15). ... The I-GALFA survey area is divided into several fields with different declination ranges. ... By starting each subsequent night at a different position, we can cover the entire map area by ``weaving'' many such tracks together to build up a complete image of the sky brightness at all positions in the field. ...

... 2007 December 3 . A Complete Solar Cycle from SOHO . ... A solar cycle is caused by the changing magnetic field of the Sun, and varies from solar maximum , when sunspot , coronal mass ejection , and flare phenomena are most frequent, to solar minimum, when such activity is relatively infrequent. ... This picture is composed of a SOHO image of the Sun in extreme ultraviolet light for each year of the last solar cycle , with images picked to illustrate the relative activity of the Sun. ...

... 96.1655Garwood+ We presented results from a continuum VLA snapshot survey of the galactic plane in the longitude range 0d < l < 90d at 1.5 GHz. Observations were taken every 0.5^o in longitude at b=0^o. Most fields are complete to about 30 mJy peak density. The positions, peak, and total flux density of 471 compact sources (<30") have been measured. ... This catalog contains results from a continuum VLA snapshot survey of the galactic plane in the longitude range 0d < l < 90d at 1.5 GHz. ...

The low-resolution, Cassegrain mounted, FORS spectropolarimeter of the ESO Very Large Telescope is being extensively used for magnetic field surveys. Some of the new discoveries suggest that relatively strong magnetic fields may play an important role in numerous physical phenomena observed in the atmospheres as well as in the circumstellar environments of certain kinds of stars. ...

The process of determining the number and characteristics of sources in astronomical images is so fundamental to a large range of astronomical problems that it is perhaps surprising that no standard procedure has ever been defined that has well understood properties with a high degree of statistical rigour on completeness and reliability. ... In this analysis we present results from testing such algorithms as implemented in the SExtractor, Selavy (Duchamp), and sfind tools on simulated data. ...
