2[nm] (ionized Calcium) absorption line
Spectroscopic observations map the Mrk 509 warm absorber, study the mini-broad absorption line
quasar PG 1126-041, determine the source of reddening in low ionization BAL quasars, and probe quasar winds using narrow intrinsic absorption lines
MeerKAT Absorption Line
Survey, led by Dr Yashwant Gupta and Dr Raghunathan Srianand, both associated with the Giant Metrewave Radio Telescope in India--4 000 hours.
The properties of atmospheric physics, the Earth's atmosphere, propagation of radiation, and molecular absorption in the atmosphere are the subjects of the introductory chapters, with separate sections on intensity and radiation flux, radiation transfer equations, and the main mechanisms of formation of the absorption line
Here the nation of France is cast seemingly as a 'faint hair-breadth line' (an absorption line
And because only WS-CRDS scans and fits the entire absorption line
profile, the HF concentration can be measured very precisely, even if there are other gas species present with absorption lines
overlapping the HF line.
The text is about 30 pages, followed by 70 pages of number lists detailing Arcturus and solar emission and absorption line
wavelengths, and another 250 pages of graphs--the atlas itself.
If one of the FBG reflectors is located near an atomic or molecular absorption line
, it can be actively stabilized to that line.
