A.6.13 Example Tables

Provided with TOPCAT are some example tables, which you can access in a number of ways. The simplest thing is to start up TOPCAT with the "-demo" flag on the command line, which will cause the program to start up with a few demonstration tables already loaded in.

You can also load examples in from the Examples menu in the Load Window however. This contains the following options:

Messier

Loads a short table containing the Messier objects

6dfgs Sample

Loads a semi-random sample of objects from the 6dfGS survey; this data is has been modified to serve as an example and is not intended for science use.

Fake Sky 1 Mrow

Loads a million-row table giving (very roughly) simulated sky objects: see Section 4.3.1 (you can easily specify similar tables with different row counts).

2d Attractor 1 Mrow

Loads a million-row table representing samples from a Clifford chaotic attractor: see Section 4.3.2 (you can easily specify similar tables with different row counts).

3d Attractor 1 Mrow

Loads a million-row table representing samples from a Rampe chaotic attractor: see Section 4.3.2 (you can easily specify similar tables with different row counts).

All Examples

Convenience item that loads all of the above tables.

Browse Demo Tree

Pops up a Hierarchy Browser looking at a hierarchy of tables in different formats. This option is designed to show some of the organisational complexity which TOPCAT can handle when browsing tables.

Note these examples are a bit of a mixed bag, and are not all that exemplary in nature. They are just present to allow you to play around with some of TOPCAT's features if you don't have any real data to hand.
