This required the addition of the tile index return parameter to smf_jsatilei2xy which also prevents the lower left tile being split. If necessary this behaviour could be controlled by a separate parameter. Since smf_jsatilei2xy checks that the tile number is valid, smf_jsatileheader need no longer do so.

This commit adjusts the numbering of the facets to follow this scheme. This is the first step towards numbering the JSA tiles using the HEALPix nested numbering scheme, which was an action item from the JSA meeting of 2013-10-28.

The offsets north-east and north-west from the southern corner of the facet are represented by the even (including 0th) and odd bits respectively. This, together with the previous commit, completes the action item from the JSA meeting on 2013-10-28 of applying the standard HEALPix nested numbering scheme to the JSA tiles.

This prevents an error when the values are subsequently fetched from the KeyMap and passed to smf_jsatilei2xy.

Otherwise small negative numbers become zero upon integer division, and coordinates within one facet below or to the left of the valid area are not rejected, leading to the generation of spurious tile indices.
