Handbook of CCD Astronomy
The above formula for the limiting magnitude of a useful spectrum should be
revised fainter by 1–2 magnitudes for a high throughput, high QE, low noise CCD
slitless spectroscopy system. All types of slitless spectroscopy must cope with
three ...

An Introduction to Active Galactic Nuclei
Stars are found to be localized in the multidimensional color space, and QSO
candidates were selected from the points which were significantly outside the
stellar locus in at least one color (Fig. 10.4). 10.3 Slitless Spectroscopy While the

Introduction to Astronomical Spectroscopy
Many modern lowdispersion spectrometers have this capability and offer this
version of slitless spectroscopy. Relative to single-object slit spectroscopy, the
simultaneous recording of many spectra by means of slitless spectroscopy can ...

One of these accelerators was equipped with a slitless flight tube and a second
machine, used for IMRT, initially had a slitted flight tube changed later to a slitless
flight tube. Sharpe et al (2000b) showed that, provided the number of MUs was ...
