Saturation is the primary concern when observing bright targets. The analog-to-digital converter will run out of bit codes at ~28,000 e - pixel -1 in the ATD-GAIN=7 (default) setting, and at ~53,000 e - pixel -1 in the ATD-GAIN=15 setting. ... Hence ATD-GAIN=15 is recommended for targets approaching 28,000 e - pixel -1 . ... For example, stars as bright as V~4.4 can be observed without saturation in F502N using the PC at ATD-GAIN=15 with a 0.11s exposure time. ...

HI spectral-line observations of galaxies (Karen O'Neil) . Measuring the width, flux, etc. of the HI profile of two galaxies, using some combination of : dwarf emission line, HVC emission line, spiral emission line, and spiral absorption line. This project was designed to demonstrate the fundamentals of spectral line observing and position switching. ... The types of galaxies observed in this project are being kept open and will be determined when the project LST is known. ...
