Best-fit parameters describing the warp.

Parameter	Case I	Case II	Case III	Case IV
(unit)
ϕ_w (deg)	178	170	178	170
a_w	1.5	1.5	2.0	2.0
$h_{w0} ({kpc}^{1 - a_{w}})$ ${h_{{\rm{w0}}}}\left( {{\rm{kp}}{{\rm{c}}^{1 - {a_w}}}} \right)$	0.194±0.017	0.136±0.006	0.083±0.011	0.052±0.002
R_w (kpc)	9.30±0.10	8.88±0.04	8.79±0.15	8.28±0.03

Notes. Best-fit parameters for the warp using the disc parameters from Model 2 from Table 4 for four different cases where we keep ϕ_w and a_w fixed.
