Spitzer Post-BCD Mosaicer: Input parameter for Pmasks

To drop all questionable pixels: PMask_Fatal_BitPattern = 16644 (bits 2,8,14)

To drop bad half of array, plus bad pixel, plus nonlinearity-affected ones: PMask_Fatal_BitPattern = 16648 (bits 3,8,14)

To drop just bad half of array, plus bad pixel: PMask_Fatal_BitPattern = 16640 (bits 8,14)

For 160 microns:

PMask_Fatal_BitPattern = 16640 (bits 8,14)
