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. ...
