在我们的原始论文中，表3中最佳拟合模型SEDs的参数和表4中所列的亚微米颗粒总质量比的推导结果引用错误。对于C/1995 O1（海尔-波普）彗星，在UT 1996 9 / 10月（相对1⁄4 2:8天文单位），1997年2月（相对1⁄4 1:21天文单位），1997年4月（相对1⁄4 0:93天文单位）和1997年6月（相对1⁄4 1:7天文单位）四个时期，SED模型拟合分别如图6-9所示，使用比原论文表3引用的Np（晶体橄榄石）大的Np（晶体橄榄石）。我们在这里给出的修改后的表3中纠正了这个错误。这个错误被传播到表4中，表4也使用了所有矿物的不正确的均匀体积密度来推导亚微米颗粒丰度的比率。考虑到亚微米非晶碳和非晶硅酸盐颗粒是多孔的（模型参数D < 3），采用碳颗粒的修正体积密度C 1⁄4 2:5 g cm3和硅酸盐颗粒的修正体积密度Si 1⁄4 3:3 g cm3，给出了修正后的表4。对于亚微米晶粒总数，得到的硅酸盐与非晶碳之比在8.1-13.3之间，明显高于我们原论文中引用的3.8-4.5。此外，Hale-Bopp彗星的硅酸盐结晶与非晶态比值在1.5-3.7之间，是我们最初引用的结晶硅酸盐/非晶态硅酸盐= 0.5-0.9范围的3 - 4倍。
In our original paper, the parameters for the best-fit model SEDs in Table 3 and the derived mass ratio of the total of submicronsized grains listed in Table 4 were incorrectly quoted. For comet C/1995 O1 (Hale-Bopp), for the four epochs UT 1996 September/ October (rh 1⁄4 2:8 AU), 1997 February (rh 1⁄4 1:21 AU), 1997 April (rh 1⁄4 0:93 AU), and 1997 June (rh 1⁄4 1:7 AU), the SED model fits shown respectively in Figures 6–9 utilize Np(crystalline olivine) larger than that quoted in Table 3 of the original paper. We have corrected this error in the revised Table 3 given here. This error was propagated into Table 4, which also used incorrect uniform bulk densities for all minerals in deriving the ratios of submicron grain abundances. A corrected Table 4 is given below, using the corrected bulk density of C 1⁄4 2:5 g cm 3 for carbon grains and of Si 1⁄4 3:3 g cm 3 for silicate grains, and taking into account that the submicron amorphous carbon and amorphous silicate grains are porous (model parameter D < 3). For the total population of submicron grains, the derived silicate-to-amorphous carbon ratio is in the range of 8.1–13.3, significantly higher than the range of 3.8–4.5 quoted in our original paper. Furthermore, for comet Hale-Bopp the silicate crystalline-to-amorphous ratio spans the range 1.5–3.7, 3 to 4 times greater than the range of crystalline silicate/amorphous silicate = 0.5–0.9 originally quoted by us.
