In this section we present plots which may be used to rapidly estimate signal-to-noise ratio (SNR) for point sources with stellar spectra observed through popular WFPC2 filters. ... One uses these plots as follows: . ... Dotted lines across the top of each plot indicate the onset of saturation. ... We look at Figure A2.10 and find this value on the horizontal axis. ... This exposure is well below the saturation lines in the plot, so saturation is not a concern. ... Figure A2.1: Point Source SNR vs. ...

... When the source-detection algorithms has run omdetect will compute raw count-rates for each detected source. For point-sources (ie those sources having widths consistent with those of the point-spread function) the count-rates are obtained by aperture photometry. For binned and unbinned images the aperture is 6 and 12 pixels, respectively. ... Extrapolate (if necessary) the source count-rate to the 12 unbinned pixel aperture, using the point-spread function for the filter. ...

This source is hiding behind our Galaxy at a distance of ~18 Mpc, located at a galactic latitide of 0 degrees. ... As we look towards longer wavelengths, 60 micron, to try and penetrate the Galactic Plane, we still see confusion from galactic sources. ... If the image seems some what confusing that is because the MOST is a continuum radio telescope and when it looks in the direction of our Galaxy it detects radiation from sources within our Galaxy and from sources that may lie behind our Galaxy. ...
