Descripción
Although the QSO PKS 2128 - 123 appears as highly variable in the I
band, with Delta-I of up to 1.69 mag, it is a moderate amplitude
variable object in the other bands of the present UBVRI observations.
Excluding these I fluxes, the average continuum is well fitted by a
power law when the Balmer continuum contribution, which enters the V
band, has been removed. The variability parameter of only about 1 day
implies a very compact source for the continuum.
