This will open a given field in the DS9 viewer.
Displaying fields can often be much easier in an interactive viewer, particularly one as versatile as DS9. This function will pixelize a field and export it to an interactive DS9 package. This requires the numdisplay package, which is a simple download from STSci. Furthermore, it presupposed that it can connect to DS9 – that is, that DS9 is already open.
Parameters : | field : strings
