Parameter	Values	Effect
`x`, `y`	Axis keys such as `sep_au`, `binding_energy_erg`, `mass_ratio_q`	Sets plotted axes.
`xlog`, `ylog`	`1` or `0`	Sets logarithmic axis scaling.
`spt_range`	`M5-L8`, `L2+`, or blank	Filters companion pairs where either component lies in the spectral range.
`comover_probability_min`	`0`-`100`	Sets the minimum CoMover probability.
`ignore_null_comover`	`1` or `0`	Hides companion rows with missing CoMover probabilities.
`*_max` sample filters	Positive numbers or blank	Sets optional maximum limits for age, proper-motion difference, distance difference, XYZ/UVW separations, and XYZ/UVW sigmas. Missing row values pass.
`ignore_null_*` sample filters	`1` or `0`	Hides rows with missing values for the matching textbox filter quantity.
`color_age`	`1` or `0`	Colors companions by adopted parent-object age.
`show_exoplanets`	`1` or `0`	Shows confirmed NASA exoplanets when compatible axes are selected.
`show_tess_candidates`	`1` or `0`	Shows TESS exoplanet candidates when axes use TESS-supported quantities.
`use_photometric_distances`	`1` or `0`	Includes rows whose adopted parent distance is photometric.
`errors`	`1` or `0`	Shows available x/y error bars.
`hover_text`	`1` or `0`	Shows or hides point hover text boxes.
`cids`, `moca_cid`	Comma-separated companion IDs	Highlights matching companions.
`max_rows`	Positive integer	Caps the companion query.
`mock`	`1`	Uses a local synthetic dataset for smoke testing.
