r: The population index, a term computed from each shower's meteor magnitude distribution. r = 2.0 - 2.5 is brighter than average, while r above 3.0 is fainter than average.
λsol: Solar longitude, a precise measure of the Earth's position on its orbit which is not dependent on the vagaries of the calendar. All λsol are given for the equinox 2000.0.
TFC and IFC: Suggested telescopic and still-imaging (including photographic) field centres respectively. β is the observer's latitude ('<' means 'south of' and '>' means 'north of'). Pairs of telescopic fields must be observed, alternating about every half hour, so that the positions of radiants can be defined. The exact choice of TFC or IFC depends on the observer's location and the elevation of the radiant. Note that the TFCs are also useful centres to use for video camera fields as well.

人口指数，任期计算从每个淋浴的座流星雨的规模分布。 r = 2.0 -2 .5是光明的高於平均水平，而r上述3 .0是f ainter高於平均水平。
λ溶胶：太阳的经度，一个确切的措施，地球上的立场，其轨道是不依赖於变幻无常的日历。所有λ溶胶给出了之为2000.0 。
天富苑及国际金融公司：建议伸缩和仍然成像（包括摄影）领域的中心。 β是观察员的纬度（ “ < '是指'南'和' > ”是指'北' ） 。对伸缩领域必须得到遵守，交替约每半小时，使的立场radiants可以被界定。确切的选择，天富苑或国际金融公司取决於对观察员的位置和高程的辐射。请注意，该tfcs ，也是一种有益的中心使用的摄像机领域以及。
