Cross-correlation and K_p–Δv_sys maps for a planetary signal injected with P = 2 days injected into DS 1 (P2). Red dotted lines/curves show the injected velocity values, whereas white dashed lines/curves show the recovered values (i.e., the values at which there was a maximum in the CCF). (a) Data reduced using the SYSREM telluric removal method. Forward model also reprocessed using SYSREM filtering technique (Gibson et al. 2022). (b) Data reduced using the MOLECFIT telluric removal method. Forward model also reprocessed by division of mean out-of-transit spectrum (see panel (c)). If this step was omitted, we found an anomalous offset from the injected K_p value.
