Description

VLA FRAMEx FITS images and SED data used in 2025arXiv250320026S separated into subdirectories by target and frequency band.

FITS images include Stokes I continuum maps, spectral index maps, and spectral index error maps. A spectral curvature map is additionally included for NGC 1068. Plots in PNG format are provided for all FITS images with contour lines set to 10 times the rms noise and [0.5, 1, 5, 10, 50, 100] mJy/beam. Scale bars indicate 1 arcsecond.

SED data contains frequency, peak flux density and RMS values per image channel in MRT format. The X-band data is measured directly from the image cube and is not corrected with the scaling offset value specified in Table 6 of 2025arXiv250320026S. Individual plots of the SEDs for each target as depicted in Figure 3 in 2025arXiv250320026S are provided (X-band correction has been applied and percent shift is indicated on the plots).
