The value field of this indexed keyword shall contain a non-negative integer, representing the number of elements along axis n of a data array. The NAXISn must be present for all values n = 1,...,NAXIS, and for no other values of n. A value of zero for any of the NAXISn signifies that no data follow the header in the HDU.
