Table 2. Crystal and parasitic Bragg reflections that cause each glitch, along with the estimated true azimuthal angle of the crystal.

The first three glitches listed here are those on the high-energy side of the central glitch C. For the corresponding glitches on the low-energy side, the 040 and 400 reflections are switched, as are the 131 and 311 reflections.

Glitch	Crystal	Reflections	True ϕ
B1	1st	400 & 311	−0.20°
B2	2nd	400 & 311	−0.16°
D	Channel cut	040 & 131	+0.06°
C	All	440 & 331	Insensitive
