  2. TOPCAT • Interactive graphical viewer and editor for tabular data. • It can examine, analyse, combine, edit and write out tables. • It understands a number of different astronomically important formats. • A million rows by a hundred columns. Francisco Jiménez Esteban – SVO – fran@laeff.inta.es Granada 27-28 de octubre de 2009

  3. TOPCAT: Control Window - The right hand panel describes the characteristics of the current table.- The buttons along the top allow launching of various other windows. Francisco Jiménez Esteban – SVO – fran@laeff.inta.es Granada 27-28 de octubre de 2009

  4. TOPCAT: Load Windows Load Data:- You can load your local tables. Francisco Jiménez Esteban – SVO – fran@laeff.inta.es Granada 27-28 de octubre de 2009

  5. TOPCAT: Load Windows Cone Search:- Service available on the web.- The list is obtained from a VO registry. Francisco Jiménez Esteban – SVO – fran@laeff.inta.es Granada 27-28 de octubre de 2009

  6. TOPCAT: Table Windows Data:- Scroll around.- Sort rows.- Define subsets. Francisco Jiménez Esteban – SVO – fran@laeff.inta.es Granada 27-28 de octubre de 2009

  7. TOPCAT: Table Windows Columns:- Information about each column.- Columns can be hidden/revealed, and new ones added. Francisco Jiménez Esteban – SVO – fran@laeff.inta.es Granada 27-28 de octubre de 2009

  8. TOPCAT: Table Windows Subsets:- See all the row subsets defined, and to define more.- Can be defined using algebraic expression, or graphically. Francisco Jiménez Esteban – SVO – fran@laeff.inta.es Granada 27-28 de octubre de 2009

  9. TOPCAT: Table Windows Statistics:- Calculate statistics for all or a selection of rows. Francisco Jiménez Esteban – SVO – fran@laeff.inta.es Granada 27-28 de octubre de 2009

  10. TOPCAT: Plot Windows • Set axis labels and ranges- Different colors or symbols for different sets of data. - Error bars- Configurable plot markers- Zoom in or out.- Select a Subset. 1D histograms:- Set bin width and offset Francisco Jiménez Esteban – SVO – fran@laeff.inta.es Granada 27-28 de octubre de 2009

  11. TOPCAT: Plot Windows 2D:- Plot pairs of columns. Francisco Jiménez Esteban – SVO – fran@laeff.inta.es Granada 27-28 de octubre de 2009

  12. TOPCAT: Plot Windows 3D:- Plots on Cartesian axes.- Rotate the axes by dragging the mouse. Francisco Jiménez Esteban – SVO – fran@laeff.inta.es Granada 27-28 de octubre de 2009

  13. TOPCAT: Plot Windows Spherical Polar:- Plots 3D plots on spherical polar axes. - Plot points only on the surface of the sphere or on the interior. - Rotate the axes by dragging the mouse. Francisco Jiménez Esteban – SVO – fran@laeff.inta.es Granada 27-28 de octubre de 2009

  14. TOPCAT: Plot Windows Stacked Line:- Plots one or more X-Y line plots using the same X axis but different Y axes. - This can be particularly useful for visualizing time-series data. Francisco Jiménez Esteban – SVO – fran@laeff.inta.es Granada 27-28 de octubre de 2009

  15. TOPCAT: Plot Windows Density Maps:- The intensity of color at each pixel reflects the number of points that fall within its bounds. - Pixel size can be changed, cut levels can be altered.- This is very useful for analysis and visualization of extremely crowded plots. Francisco Jiménez Esteban – SVO – fran@laeff.inta.es Granada 27-28 de octubre de 2009

  16. TOPCAT: Match Windows Concatenate:- Concatenate the rows of existing tables to create new ones. Francisco Jiménez Esteban – SVO – fran@laeff.inta.es Granada 27-28 de octubre de 2009

  17. TOPCAT: Match Windows 1 Table:- Mark groups of rows.- Eliminate All grouped.- Eliminate All but First.- New tables with groups. Francisco Jiménez Esteban – SVO – fran@laeff.inta.es Granada 27-28 de octubre de 2009

  18. TOPCAT: Match Windows 2 Tables:- Specify a match operation which will join two tables. - A wide range of multivariate matches is possible. Francisco Jiménez Esteban – SVO – fran@laeff.inta.es Granada 27-28 de octubre de 2009

  19. TOPCAT: Functions Windows Available Functions:- Displays the details of the functions which can be used to define new columns and subsets. Francisco Jiménez Esteban – SVO – fran@laeff.inta.es Granada 27-28 de octubre de 2009

  20. STILTS STILTS is a set of command-line tools for processing tabular data. Its facilities:- Cross-matching- Format conversion and validation- Column calculation and rearrangement- Row selection- Sorting- Plotting- Statistical calculations- Metadata display Francisco Jiménez Esteban – SVO – fran@laeff.inta.es Granada 27-28 de octubre de 2009

  21. STILTS - Accept streamed data so the size of tables which can be processed is not limited by available memory.- In general, the form of a command isjava –jar /path/stilts.jar <stilts-flags> <task-name> <task-args> Francisco Jiménez Esteban – SVO – fran@laeff.inta.es Granada 27-28 de octubre de 2009
