Position, redshift, and mass of the two pairs of target galaxy clusters analysed in this work.
| Right Ascension | Declination | Mass | ||
|---|---|---|---|---|
| Target | (J2000) | (J2000) | Redshift | (M⊙) |
| A399 | 02h57m56s | +13°00′59″ | 0.072 | ∼5.7 × 1014 |
| A401 | 02h58m57s | +13°34′46″ | 0.074 | ∼9.3 × 1014 |
| A21 | 00h20m52s | +28°30′30″ | 0.094 | ∼3.8 × 1014 |
| G114.9 | 00h21m13s | +28°15′00″ | 0.095 | ∼2.5 × 1014 |
Notes. For the A399-A401 pair, the mass was X-ray derived by Chandra (Vikhlinin et al. 2009), while for A21-G114.9 it is the SZ-derived value (as defined in Planck Collaboration VIII 2013).
