Modern catalogs put Epsilon Eridani's total proper motion at about 975 mas/yr (≈ 0.975 arcsec/yr), not 0.962 arcsec/yr.

• NASA Exoplanet Archive lists proper motion components of −975.376 mas/yr in RA and +20.2655 mas/yr in Dec, with a Total Proper Motion of 975.5865 mas/yr.
• SIMBAD likewise lists −974.758 mas/yr and +20.876 mas/yr, which also combine to about 975 mas/yr.

Even if you use the article's own rounded components (0.976 and 0.018 arcsec/yr), the combined motion is:

sqrt(0.976^2 + 0.018^2) ≈ 0.976 arcsec/yr

So 0.962 arcsec/yr is not the correct combined total.

Current reference catalogs do not support +15.5 km/s as Epsilon Eridani's heliocentric radial velocity.

• SIMBAD gives a radial velocity of 16.376 km/s with a very small quoted error, sourced to Soubiran et al. 2018.
• NASA's Exoplanet Archive compiles published stellar-parameter solutions for Epsilon Eridani with radial velocities around 16.0 ± 0.1 km/s, 16.3 km/s, and 17.3 km/s.

That means the article's +15.5 km/s figure is inconsistent with modern catalog values and is not just a rounding of the current measurement. A modern value would be approximately +16.4 km/s (or whatever specific cited source the article intends to use).
