资源简介:
This dataset contains 5-min omnidirectional fluxes for He, C, O, Ne, Si, and Fe in particles/cm2-sr-s-MeV/nuc in seven energy bins (six for Ne) in the general range of 2-10 MeV/nucleon. The error bars are statistical only, that is, corresponding to sqrt(N), where N is the number of collected ions. For intervals in which zero ions were observed, the error bar corresponds to one ion. ASCII listing generated from this link provide the start-time of the averaging interval as YYYY DD HH, followed by pairs of numbers giving the flux and its uncertainty from the selected intervals. The available energy bins for the species are: +----------------------------------------------------------------------------------------------+ | Species | Band 1 | Band 2 | Band 3 | Band 4 | Band 5 | Band 6 | Band 7 | |----------------------------------------------------------------------------------------------| | He | 2.00-2.40 | 2.40-3.00 | 3.00-3.70 | 3.70-4.53 | 4.53-6.00 | 6.00-7.40 | 7.40-9.64 | | C | 2.57-3.19 | 3.19-3.85 | 3.85-4.80 | 4.80-5.80 | 5.80-7.20 | 7.20-9.10 | 9.10-13.70 | | O | 2.56-3.17 | 3.17-3.88 | 3.88-4.68 | 4.68-6.00 | 6.00-7.40 | 7.40-9.20 | 9.20-13.40 | | Ne | 3.27-3.98 | 3.98-4.72 | 4.72-5.92 | 5.92-7.87 | 7.87-9.96 | 9.96-12.7 | | | Si | 2.50-3.20 | 3.20-4.00 | 4.00-4.90 | 4.90-6.00 | 6.00-7.90 | 7.90-9.70 | 9.70-13.60 | | Fe | 2.40-3.00 | 3.00-3.95 | 3.95-4.80 | 4.80-5.90 | 5.90-7.80 | 7.80-9.30 | 9.30-12.50 | +----------------------------------------------------------------------------------------------+

本数据集涵盖氦(He)、碳(C)、氧(O)、氖(Ne)、硅(Si)及铁(Fe)的5分钟全向通量数据,单位为粒子/(平方厘米·立体角·秒·兆电子伏/核子),共设置7个能段(氖仅设6个能段),能段整体覆盖范围为2~10 MeV/核子。 该数据的误差棒仅为统计误差,即误差值对应√N,其中N为采集到的离子总数;对于未观测到任何离子的时段,其误差棒对应1个离子的计数。 通过该链接生成的ASCII格式清单中,首先以YYYY DD HH的格式给出平均时段的起始时间,随后依次给出各选定时段的通量及其不确定度的数值对。 各粒子物种的可用能段如下: +----------------------------------------------------------------------------------------------+ | 元素物种 | 能段1 | 能段2 | 能段3 | 能段4 | 能段5 | 能段6 | 能段7 | |----------------------------------------------------------------------------------------------| | 氦(He) | 2.00-2.40 | 2.40-3.00 | 3.00-3.70 | 3.70-4.53 | 4.53-6.00 | 6.00-7.40 | 7.40-9.64 | | 碳(C) | 2.57-3.19 | 3.19-3.85 | 3.85-4.80 | 4.80-5.80 | 5.80-7.20 | 7.20-9.10 | 9.10-13.70 | | 氧(O) | 2.56-3.17 | 3.17-3.88 | 3.88-4.68 | 4.68-6.00 | 6.00-7.40 | 7.40-9.20 | 9.20-13.40 | | 氖(Ne) | 3.27-3.98 | 3.98-4.72 | 4.72-5.92 | 5.92-7.87 | 7.87-9.96 | 9.96-12.7 | | | 硅(Si) | 2.50-3.20 | 3.20-4.00 | 4.00-4.90 | 4.90-6.00 | 6.00-7.90 | 7.90-9.70 | 9.70-13.60 | | 铁(Fe) | 2.40-3.00 | 3.00-3.95 | 3.95-4.80 | 4.80-5.90 | 5.90-7.80 | 7.80-9.30 | 9.30-12.50 | +----------------------------------------------------------------------------------------------+
