Next: Discussion Up: Iterative/Recursive Deconvolution with Application Previous: Test Results . There have been several investigations of the photometric properties of HST image restoration techniques utilizing a range of different algorithms. ... They used that technique to restore a simulated image of a crowded field. ... Cohen (1991) investigated the reliability of the Maximum Entropy method (Skilling 1989, Gull 1989) in restoring astronomical images while preserving photometric accuracy. ...

... 12.07.07 Nando - Test the magnitude of aperture corrections to Landoldt Apertures. ... 12.07.07 Palle - Write up some suggestions for tests to verify which FORS/UT combinations really have rotating features. Original text: Sabine's flatfield versus rotators angle look promising, but more tests should be done which do not depend on the structure looking like a finger. ... The halves could be either ordered by rot-angle (e.g. 0-180 together, 180-360 together), or totally random. ...

... Previous: ESO C Library for an Image Processing Software Environment (eclipse) . ... A new CLEAN-type algorithm searches for model components not in the dirty image but in the multi-resolution wavelet transform of the dirty image based on the dirty beam. ... The improvement of this prototype Wavelet CLEAN, which does convolve with the dirty beam, can be attributed to a suppression of noise and aliasing in the dirty image by use of information in the sidelobes of the whole image domain. ...

Next: Rapidly Rotating Stars Up: Discussion Previous: Relations . ... They attributed this to a mechanism which regulated stellar angular momentum through the accretion disk. ... While some of this may be due to sampling effects, the data seem to indicate that after a star loses its disk, either it continues its slow rotation for a period of time and then a rapid increase in rotation rate commences or spin up does not necessarily follow the loss of the disk. ...

... In Fig. 2 the spectrum of the host galaxy HS1035+4758 is shown, in which typical HII-galaxy narrow emission lines are seen: H 4861, [OIII] 4959,5007, H 6562, [NII] 6548,6584 and [SII] 6716,6731 ?. ... The spectral evolution of SN 1998bv is illustrated in Fig. ...

... Unlike clients such as Shout and IceDJ this permits the broadcast of live audio, rather than prerecorded mp3's. LiveIce was developed after the appearance of IceCast to provide the Real Time streaming functionality which makes it a viable solution for broadcasting.
