Astronomical Photometry: A Guide
Consequently, Eq. (1.39) cannot be valid. It is, of course, possible to find, for
every observation, a particular wavelength where monochromatic measurements
would reproduce the heterochromatic data. The isophotal wavelength X\ is
precisely ...

Fourth, in most E galaxies the isophotal ellipticity changes as a function of radius.
It can increase, decrease, or vary irregularly with increasing radius (Liller 1961;
King 1978; Jedrzejewski 1987a; Franx et al. 1989a; and many since).
R. C. Kennicutt, F. Schweizer, J.E. Barnes, 1998
2.3.6 Surface brightness and isophotal radii To this point we have been
concerned with total brightnesses and luminosities. Galaxies, unlike most stars,
are resolved objects, so that in addition to measuring the total radiative flux from
a galaxy, ...

Isophotal Contour Densitometer
Because of the limitations for this work of other contouring methods the staff of the High Altitude Observatory has sought to develop a new type photometer capable of analyzing films from motion picture sequences fast enough for the problem ...

Chaos in Astronomy: Conference 2007
We show that disc mergers alone are unlikely to form a boxy-discy dichotomy in
isophotal shape, because of the survival of disc-like orbits even in violent
mergers. The shape of the different orbit families can vary strongly, depending on
how ...
