Running catgrid

To generate a grid from columns in a catalogue type:

catgrid

By default catgrid generates an un-normalised grid. To generate a normalised grid type:

catgrid  normal=true

There must be one or more spaces between `catgrid' and `normal=true'. You then answer the prompts described below. In the descriptions the prompts are identified by the corresponding ADAM parameter name, which appears at the start of the prompt line.

CATIN

Enter the name of the input catalogue.

NDIM

Enter the dimensionality of the output grid. The permitted values are one to three.

COLX

Enter the name of the column to be used for the first ($x$) axis of the grid.

XBINS

Enter the number of bins required along the first ($x$) axis of the grid.

If you specified a dimensionality of two or three then prompts corresponding to COLX and XBINS for the second ($y$) and third ($z$) axis are issued, as appropriate.

GRID

Enter the name of the file to contain the output grid. Note that NDF files have file type `.sdf', but the name should be entered without the file type.
