... A demonstration of HST WFPC image restoration has been made using both empirical and simulated PSFs. Empirical PSFs are obtained from the WFPC PSF library and also extracted from the image to be restored. ... The best results obtained thus far rely upon being able to determine a high S/N empirical PSF from the data frame. In order to achieve accurate restorations of data with high dynamic range excellent PSF models are required. ... Keywords: image restoration, HST WFPC image, PSFs . ...

Ideally the in-orbit PixToPixSens file will be generated from internal calibration measurements using the fullframe high resolution engineering mode. However due to their large data volume the fullframe high resolution data won't be available frequently enough to base the in-flight generation of the PixToPixSens file on the high resolution data. ... i.e. the average counts per pixel per CCD-frame . ...

... 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. ...

Declare the data file with the data command, see section How should I get data into SM? , or you could see section 'Data' in The SM Manual . ... If you want to plot points, you should first define the point style with the ptype command. ptype allows you to define the point as a type of polygon, with any number of sides, and 4 basic forms (see section 'Ptype' in The SM Manual ). ...

... ALMA . ... OOF software . ... Software . ... We present a framework for modelling atmospheric phase errors and their correction by both the fast-switching and water vapour radiometeric techniques. Notable features are simulating three dimensional turbulent volumes instead of flat phase screens, considering three representative configurations of ALMA and parametrisation in terms of phase fluctuations on a 300m baseline, allowing referencing to the site-testing interferometer data. ...

Here are the two Perl programs I use to generate the sounds on this web page. playlines.pl , generates synthetic spectra made up of Gaussian emission lines and power-law or black body continuum, and converts them into sounds. specsound.pl , Reads in an ASCII spectrum and converts it into a sound. Both programs rely on the MATH::FFT perl module available here . You will also need the SoX utility to convert the resultant ASCII waveforms into .wav files. SoX is available here . ...

Medium Deep Survey Information The question of the legacy left by E-ALFA is one that we need to think very carefully about. ... We present here some possible parameters for such a survey. Survey Science Objectives and Benefits: · HI mass function over a range of environments: A deep survey will be much more effective at probing the HI mass function over a range of environments (if the regions surveyed are well chosen) because it will probe more independent volumes than a shallower survey. ...
