- 1: Category / Unit of the axis for plot
- 2: Quantity / Element of the axis
- 3: Quantity in text format. [Fe/H], [C/Fe], [C/N], ... any combinations of [X/Y
] are supported.
- 4: Allowed range of quantity. Set blank if unset.
- 5: Options to choose if include/exclude the data with upper limit.
- 6: Search by object name. "HE0107-5240", "CS", "0107", etc are allowed.
- 7: Subtract binary stars with the range of binary period.
- 8: Criterion on the photometric magnitude. Choose photometric band and range.
- 9: Criterion on the wavelength resolution.
- 10: Search by author.
- 11: Criterion on the original journal. COLOR(RED): do not work.
- 12: Criterion on the publshed year of original journal. COLOR(RED): do not work.

- 15: Priority for the choice of plotted data. 'Year' means that the latest data are preferentially adopted. COLOR(RED): do not work.
- 16: Plot option group by threshoulds (C-rich or C-norma., RGB or MS, EMP or MP) or one plot data for one object.
-- C-rich : [C/Fe] > 0.5
-- RGB : Teff < 6000 and log g < 3.5
-- EMP : [Fe/H] < -2.5
- 17: Cross search option. Choose if the combinationn of data across papers is allowed or not.
