How to deal with mask bits in your top level code.

        /* Make sure the mask planes are there and consistent */
        int badMaskBitT = templateMaskedImage.getMask()->getMaskPlane("BAD");
        if (badMaskBitT == -1) {
            /* It doesn't exist yet */
            badMaskBitT = templateMaskedImage.getMask()->addMaskPlane("BAD");
        }
        int badMaskBitI = scienceMaskedImage.getMask()->getMaskPlane("BAD");
        if (badMaskBitI == -1) {
            /* It doesn't exist yet */
            badMaskBitI = scienceMaskedImage.getMask()->addMaskPlane("BAD");
        }
        assert(badMaskBitT == badMaskBitI);

        int edgeMaskBitT = templateMaskedImage.getMask()->getMaskPlane("EDGE");
        if (edgeMaskBitT == -1) {
            /* It doesn't exist yet */
            edgeMaskBitT = templateMaskedImage.getMask()->addMaskPlane("EDGE");
        }
        int edgeMaskBitI = scienceMaskedImage.getMask()->getMaskPlane("EDGE");
        if (edgeMaskBitI == -1) {
            /* It doesn't exist yet */
            edgeMaskBitI = scienceMaskedImage.getMask()->addMaskPlane("EDGE");
        }
        assert(edgeMaskBitT == edgeMaskBitI);
