Abstract:
We present 5321 mas-resolution total intensity and linear polarization
maps of 437 active galactic nuclei (AGNs) obtained with the VLBA at
15GHz as part of the MOJAVE survey, and also from the NRAO data
archive. The former is a long-term program to study the structure and
evolution of powerful parsec-scale outflows associated with AGNs. The
targeted AGNs are drawn from several flux-limited radio and
γ-ray samples, and all have correlated VLBA flux densities
greater than ∼50mJy at 15GHz. Approximately 80% of these AGNs are
associated with γ-ray sources detected by the Fermi LAT
instrument. The vast majority were observed with the VLBA on 5-15
occasions between 1996 January 19 and 2016 December 26, at intervals
ranging from a month to several years, with the most typical sampling
interval being six months. A detailed analysis of the linear and
circular polarization evolutions of these AGN jets is presented in the
other papers in this series.
Description:
The VLBA maps in this paper are of 437 compact, radio-loud AGNs
observed as part of the MOJAVE program.
The data consist of 5321 observations of 437 AGNs in the 15GHz band,
obtained between 1996 January 19 and 2016 December 26 with the VLBA in
full polarization mode (Table 2). Most of the VLBA observations (86%)
were carried out as part of the MOJAVE program (Paper V; Lister+ 2009,
J/AJ/137/3718), while the remainder were downloaded from the NRAO
archive. Most of the AGNs have between 5 and 15 VLBA observation
epochs, although a substantial number have considerably more epochs.

Note (1): Upper limit based on three times the P rms noise level.
Note (2): Figure 4 gives the 15GHz VLBA maps of the MOJAVE AGN sample.
Each panel contains two contour maps of the radio source, the first
consisting of I contours in successive integer powers of two times
the lowest contour level, with linear fractional polarization overlaid
according to the color wedge. A single negative I contour equal to the
base contour level is also plotted.
The second map includes the lowest positive I contour from the first
map, and linearly polarized intensity contours, also in increasing
powers of two. The sticks indicate the electric polarization vector
directions, uncorrected for Faraday rotation. The FWHM dimensions and
orientation of the elliptical Gaussian restoring beam are indicated by
a cross in the lower left corner of the map.
