... Infrared observations of RCBs show that, even at maximum light, there are copious amounts of dust surrounding the star ([ Kilkenny & Whittet 1984 ], [ Walker 1985 ]). A very interesting result is that during a decline, when the V-band brightness is plummeting, the infrared L-band brightness shows no significant change and continues to show pulsational variations [ Feast et al. ... Therefore the obscuring dust can only cover a fraction of the stellar surface. ...

HI excess emission in the same velocity range . 0 N(HI) ~(0.6-1.3) 1021 cm-2 , <n(HI)>=1.7-9 cm-3 . The argument by Williams et al is little bit different. They found HISA associated with some limited areas of RMC. Then they used the HI emission at the same velocity interval to derive a mean density between 1.7 and 9.
