Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

The pkg for calculating atmospheric refraction.

Readme

AtmosphericRefraction

简介

AtmosphericRefraction 是一个基于 NodeJS 开发的大气折射计算工具,可修正大气折射对地平高度所产生的影响。

安装

通过 npm 安装,在你的 node 项目目录下执行:

npm i --save @behaver/atmospheric-refraction

安装完成后,调用即可:

const AtmosphericRefraction = require('@behaver/atmospheric-refraction');

用例

const AtmosphericRefraction = require('@behaver/atmospheric-refraction');

// 实例化大气折射对象
let ar = new AtmosphericRefraction({
  T: 23, // 海平面温度,单位:摄氏度
  P: 1018, // 海平面大气压强,单位:百帕
  apparentH: 23.456, // 视地平高度,单位:度
});

// 获取真地平高度,单位:度
let trueH = ar.trueH;

// 输出高度修正值
console.log(ar.R);

API

constructor(options)

构造函数,接口同 init 方法

init(options)

初始化方法

规定参数:

  • options.T 温度,单位:摄氏度
  • options.P 大气压强,单位:毫巴/百帕
  • options.apparentH 视地平高度,单位:度
  • options.trueH 真地平高度,单位:度
  • options.isStrict 是否精确修正(考虑气压、温度影响)

set apparentH(h0)

设置 视地平高度(单位:度)

set trueH(h)

设置 真地平高度(单位:度)

set T(t)

set P(p)

设置 大气压强设定(单位:百帕)

set isStrict(isStrict)

设置 是否进行精确修正

get apparentH()

获取 视地平高度(单位:度)

get trueH()

获取 修整大气折射后的真地平高度(单位:度)

get r()

获取 大气折射修正值(单位:度)

get R()

获取 大气折射修正值(包含温度和大气压强修正,单位:度)

get T()

获取 温度设定(单位:摄氏度)

get P()

获取 大气压强设定(单位:百帕)

get isStrict()

获取 是否进行精确修正设定
