This attribute specifies the order for the WCS axes in any new FITS-WCS headers created using the AST_WRITE method.

The value of the FitsAxisOrder attribute can be either " $<$auto$>$" (the default value), "$<$copy$>$" or a space-separated list of axis symbols:

"$<$auto$>$" : causes the WCS axis order to be chosen automatically so that the i’ th WCS axis in the new FITS header is the WCS axis which is more nearly parallel to the i’ th pixel axis.

"$<$copy$>$" : causes the WCS axis order to be set so that the i’ th WCS axis in the new FITS header is the i’ th WCS axis in the current Frame of the FrameSet being written out to the header.

" Sym1 Sym2..." : the space-separated list is seached in turn for the Symbol attribute of each axis in the current Frame of the FrameSet. The order in which these Symbols occur within the space-separated list defines the order of the WCS axes in the new FITS header. An error is reported if Symbol for a current Frame axis is not present in the supplied list. However, no error is reported if the list contains extra words that do not correspond to the Symbol of any current Frame axis.
