TableHDU

         throws FitsException

Build a table from the specified FITS header.

Parameters:

header - to use as a template.

FitsException - if the header was not valid.

Method Detail

addColumnString

public void addColumnString(String keyBase)

Add a base keyword to the keys to be looked for in describing a column. E.g., if a user wishes to make sure the TLMINn keywords are associated with columns he/she might call addColumnString("TLMIN"); This does not mean that the software will generate these columns, only that they will be seen as associated with the appropriate table data.

setLastMark

void setLastMark(int lastMark,
                 int colNumber)

Ensure that keywords for the current column are placed after the keywords for the last column.
