... ARC 3.5m | ... 2.1 Choosing and Exposure Time . 2.2 Choosing the CCD Gain . ... 3.2 Read Times and Read Noise . ... At the slow read rate of 100 KHz to be used for exposure times longer than a few seconds, we determine an average read noise of order 3.7 ? ... Table 2: Exposure time must be greater than the readout time by at least 0.03 s. The Agile CCD camera has two readout amplifiers, one of which is capable of reading at the fast readrate of 1MHz while introducing a read noise of order 7 ? ...

... An interactive IRAF task for the analysis of Extreme Ultraviolet Explorer ( EUVE ) emission line spectra is presented. The line flux in extracted spectra may be measured by multiple techniques, including fitting individual lines. ... To aid in identifying lines, the positions of known lines may be marked on the spectrum during the fitting process. Also, model EUVE spectra may be constructed and overlaid using plasma emissivities and source emission measures supplied by the user. ...
