UNIONS: A direct measurement of intrinsic alignment with BOSS/eBOSS spectroscopy

Table 3.

Luminosity and intrinsic alignment amplitudes for the CMASS samples split into luminosity bins.

	log⟨L/L₀⟩	A_IA
CMASS-UNIONS L1	−0.26	$2 . 74_{- 0.59}^{+ 0.59}$ $2.74^{+0.59}_{-0.59}$
CMASS-UNIONS L2	−0.06	$4 . 08_{- 0.54}^{+ 0.54}$ $4.08^{+0.54}_{-0.54}$
CMASS-UNIONS L3	0.15	$5 . 07_{- 0.55}^{+ 0.55}$ $5.07^{+0.55}_{-0.55}$
CMASS-DES L1	−0.29	$1 . 5_{- 1.1}^{+ 1.1}$ $1.5^{+1.1}_{-1.1}$
CMASS-DES L2	−0.12	$3 . 9_{- 1.3}^{+ 1.3}$ $3.9^{+1.3}_{-1.3}$
CMASS-DES L3	0.07	$4 . 0_{- 1.2}^{+ 1.2}$ $4.0^{+1.2}_{-1.2}$

Notes. Both CMASS-UNIONS and CMASS-DES show very strong scaling with luminosity.
