Also de-redden.
[f. de- II. 1 + redden v.]
trans. To correct the observed spectrum of (a star, etc.) for the reddening of its light by interstellar material, so as to arrive at its intrinsic spectrum. Also with the observed spectrum as obj.
1971Astron. & Astrophysics X. 270 The 41 stars..were individually dereddened by the ‘Q-method’ of Johnson. 1976Ibid. L. 446/2 We can estimate the amount of extinction..by dereddening the observed spectrum until a smooth flux distribution..is obtained. 1978Nature 5 Oct. 412/2 All the observed data are de-reddened using E(B - V) = 0.06..and the extinction law of Code et al. in the UV. 1985Astron. & Astrophysics CXLIII. 455/1 H 1286 can be dereddened to a position on the ZAMS.
Hence deˈreddened ppl. a., deˈreddening vbl. n.
1971Astron. & Astrophysics X. 275/2 Individual dereddened values of B-V were determined. 1979Nature 19 Apr. 719/1 To obtain the observed (dereddened) anomalous line luminosity, we find that the particle density in the emitting region is ∼1012cm-3. 1985Astron. & Astrophysics CXLIII. 457/1 Dereddening moves H 1286 to the ZAMS. |
