Tutorial for the SAGA database Retrieval subsystem

This version of tutorial is obsolete. To be updated soon.

This tutorial explains the meanings of the options and columns displayed on the retrieval subsystem and shows how it works.

Top page

  • A-1: Date of last update of the SAGA database in JST
  • A-1: Button for executing search
  • A-1: Button for setting search example (currently not working)
  • A-1: Button for reset the form
  • B-1: Category / Unit of the axis for plot as shown below

  • B-2: Quantity / Element of the axis
  • B-3: Quantity in text format. [Fe/H], [C/Fe], [C/N], … any combinations of [X/Y ] are supported.
  • B-4: Allowed range of quantity. Set blank if unset.
  • B-5: Options to choose if include/exclude the data with upper limit.
  • C-1: Search by object name. “HE0107-5240”, “CS”, “0107”, etc are allowed.
  • C-2: Subtract binary stars with the range of binary period.
  • C-3: Criterion on the photometric magnitude. Choose photometric band and range.
  • C-4: Criterion on the wavelength resolution.
  • D-1: Search by author.
  • D-2: Criterion on the original journal. do not work.
  • D-3: Criterion on the publshed year of original journal. do not work.
  • E-1: Number of display per result page.
  • E-2: Sort option for the result. do not work.
  • E-3: Priority for the choice of plotted data. ‘Year’ means that the latest data are preferentially adopted. do not work.
  • E-4: 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] > 0.7 ([C/Fe] > 0.5 before 31, Oct. 2010 version)
         RGB : Teff < 6000 and log g < 3.5
         EMP : [Fe/H] < -2.5
  • E-5: Cross search option. Choose if the combinationn of data across papers is allowed or not.

Search Result

  • A-1: Plot data for objects with selected checkboxes
  • A-2: Destroy all internal set-ups and go to top page
  • A-3: Reset the form
  • A-4: Plot data for all objects retrieved
  • A-5: Show previous/next page
  • A-6: Change the page. The current page is shown by green button.
  • B-1: ID for object
  • B-2: Tick all the checkboxes in the current list
  • B-3: Add to plot list for the object
  • B-4: Object name group by references. Each object has a link to the page to see more info. of the object.
  • B-5: Reference code. Each reference code has a link to the page to see more info. of the paper.
  • B-6: Metallicity, Effective temperature, and Surface gravity of the object adopted by the paper.
  • B-7: Values of X-axis, Y-axis, and criterion axis derived by the paper.
  • B-8: Choose the dataset for derived values for X- and Y-axis. It is allowed that users can plot one data set for single object.

Data plot

  • A-1: Plotted data are automatically classified into 7 categories according to the following criteria.
    • EMP: stars with [Fe/H] ⇐ -2.5. Although the value of [Fe/H] depends on the observations, it is simply taken from the data in the most recent published paper, the largest resolution for observing set ups, and the smallest error bars. Fe I is preferably adopted for identical paper.
    • C-rich: stars with [C/Fe] > 0.7. The selection condition of the data is the same as for EMP. “CEMP” means “C-rich” and “EMP”.
    • RGB: stars with Teff < 6000 K and log g < 3.5. Otherwise, the star is classified as “MS”.
  • A-2: Number of plotted data (top) and Pearson coefficient for plotted data (bottom). In calculating the coefficient, data with upper limit are excluded.
  • A-3: Arrows show the upper limits for derived values.
  • A-4: Panel is the clickable map. Each plotted data has a link to the page to see more info. of the object.
  • B-1: Set title of the figure
  • B-2: Specify the position of the legend or unset the legend
  • B-3: Set labels for X- and Y-axis.
  • B-4: Set the scale of the figure in linear or log
  • B-5: Set the range of values. Use “*” for automatic scale.
  • B-6: Include or exclude the data with upper limits. Currently it is not working.
  • C-1: Replot the data
  • C-2: Reset the form
  • C-3: Delete all the list of plotted data
  • C-4: Destroy all internal set-ups and go to top page
  • C-5: Data ID. Each ID has a link to the text data.
  • C-6: Add to the plot list in the figure. Untick the checkbox if you want to see figure without certain category[categories].
  • C-7: Legend of each data set. Users cannot edit these forms.
  • C-8: Resize the data points
  • C-9: Change the symbol of the data points
  • C-10: Remove the data set from the plot list
  • D-1: Options for creating figures with/without color
  • D-2: Links to the current figures in different format
  • D-3: Button to download all the data and script to reproduce the figure.
  • D-4: Link to the file upload system, which opens in new window. See below for more detail.
