2. Optimization of spectroscopic observations
... Let us first find out which way -- rise in spectral resolution with some loss in the S/N ratio or increase in the S/N ratio with a fixed spectral resolution -- is better for the purpose of reduction of equivalent width determination errors. ... N -- number of counts for 1 ? ... line equivalent width, . ... Thus if the spectral resolution is managed to be increased (i.e. to decrease )without loss in the number of counts falling at 1 ?, the equivalent width measurement error is then proportional to . ...

5. Spectra of 300 sources
... 1Wills Accurate measurements of relative flux density have been made between frequencies of 468 and 5009 MHz for 300 radio sources selected from Parkes catalogue. ... Excluding the incertainties in scaling these flux densities to an absolute system, rms errors vary from 0.24 Jy and 2.4 % at 635 MHz to 1.8 % at 2700 MHz; uncertainties in "absolute" scaling are thought to be about 45 %. ... Some sources whose spectra may be useful for flux density calibration are noted. ...
