Notes. Column 3: right ascension; Col. 4. Declination; Col. 5. Frequency; Col. 6. Flux density; Col. 7. Spectral index^a; 8. Largest linear size.

^(a)

The spectral index (α) is between the frequencies reported in two consecutive rows, unless stated in the comments.

^(b)

May be contaminated by the extended components of A that are missed in FIRST.

^(c)

VLA C-array data at 4.89 GHz (Giacintucci et al., in prep.).

^(d)

Difference between the total flux density in low resolution image around S1 and that of S1 in high resolution image.

^(e)

Difference between NVSS and FIRST flux densities.

^(f)

May be affected by over-subtraction of point source flux density.
