Comparative intensity and density mapping of NGC 40
Published online by Cambridge University Press: 25 May 2016
Extract
Two dimensional spectro-imaging of the planetary nebula NGC 40 was done to create spatially resolved intensity and electron density images. The CCD images, taken in Hβ, [S ii] λ6717, and [S ii] λλ6717, 6731, were calibrated, then correlated using previously published spectroscopic and photometric data of NGC 40 as a flux standard.
