<h2 id="配置订阅源">配置订阅源</h2>
<p>想要使用newsboat，首先要设置订阅源，否则连界面都无法打开。
编辑<code>~/.newsboat/urls</code>文件，从而设置订阅源。具体方法就是将网址一行一行地写进这个文件中。</p><p>在这里给出一个示例文件（此内容只用于示例，作者本人对订阅源内容所表述的任何事物不负连带责任）</p><pre><code>https://marc.stic.work/feed.xml

<p>另外想要了解更多关于Web Feed相关信息，可以参考<a href="https://wiki.archlinux.org/title/Web_feed">https://wiki.archlinux.org/title/Web_feed</a></p><h2 id="使用-1">使用</h2>
<p>在配置完订阅源之后可以直接使用<code>newsboat</code>命令来使用。</p><p>值得注意的是，在绝大部分unix系统的TTY中是没有中文支持的，所以建议有条件的情况下最好在正常的现代化虚拟终端，如Terminal、Iterm2等等中使用，而不是在如Ubuntu Server无图形界面的TTY中使用，当然只阅读英文的订阅源是不存在任何问题的。</p><h1 id="其他配置">其他配置</h1>
<p>newsboat的配置文件在<code>~/.newsboat/conf</code>中，直接编辑这个文件可以来修改newsboat的设置。同样在这里给出一个配置文件的示例，具体参数可以去参考官网。</p><pre><code># general settings

<h1 id="euclid">Euclid</h1>
<p>The overall active mission duration for Euclid is planned to be at least 6.5 years, with main survey operations lasting 6 years after an initial commissioning phase of 3 months following launch. If Euclid continues to be operational after this time, a mission extension could follow with additional surveys. Well characterized and validated data will be made public in three main data releases (DR1, DR2, DR3), phased with the survey progress, with the final DR3 a year after the end of the main survey.</p><p>Preceding each major DR are “quick releases” (Q1, Q2, Q3, Q4) of selected areas and data-products, to demonstrate the data to be expected, and to allow scientists to sharpen their data analysis tools.</p><figure class="post__image"><img loading="lazy" src="/Users/marcshen/Downloads/time.jpg" alt="time" data-is-external-image="true"></figure><p>The main component of the Q1 data shall contain Level 2 data of a single visit (at the depth of the <a href="https://euclid.caltech.edu/page/euclid-wide-survey">Euclid Wide Survey</a>) over the <a href="https://euclid.caltech.edu/page/euclid-deep-fields">Euclid Deep Fields</a> (EDFs): 20 deg2 of the EDF North, 10 deg2 of EDF Fornax, and 23 deg2 of the EDF South. The deep fields will be visited multiple times during the mission. Click <a href="https://www.cosmos.esa.int/documents/10647/12245842/EUCL-EST-ME-8-007_v11_EST_Q1_memo_2022-10-06.pdf">here</a> for the scope and content of Q1, and <a href="https://www.cosmos.esa.int/documents/10647/12245842/EUCL-EST-ME-8-014_v10_Q1_product_definition_2023-08-14.pdf">here</a> for the product definition of Q1.</p><p>Euclid will carry out two types of surveys:</p><ul>
<li>The Wide Survey covering ~15000 (deg)2 of the extragalactic sky, the main survey of the mission.</li>
<li>Deep Fields totaling~ 50 (deg)2 of deep fields and calibration observations regularly interleaved within the main survey schedule.</li>
</ul>
<p><strong>Key Information on the Euclid Wide Survey:</strong></p><ul>
<li>Core survey, required to meet mission objectives.</li>
<li>~15000 (deg)2, nearly half of the extragalactic sky.</li>
<li>VIS imaging of galaxy shapes down to AB magnitude 24.5 (10 σ, extended source)</li>
<li>NISP photometry in the Y, J and H near-infrared bands (0.92 – 2.0 µm) reaching AB magnitude 24 (5σ, point source) corresponding to a photometric redshift accuracy of σ(z)/(1+z)<0.05</li>
<li>Parallel to the VIS exposures, NISP will measure redshifts with σ(z)/(1+z)<0.001 of at least 1700 galaxies/(deg)2 with a completeness higher than 45% at a detection limit of 2×10-16 erg/s/cm2 (3.5σ) for a typical source of 0.5 arcsec in the wavelength range 1.25-1.85 µm (the red grism). </li>
<li>The detailed description of the Euclid Wide Survey can be found in <a href="https://ui.adsabs.harvard.edu/abs/2022A%26A...662A.112E/abstract">Scaramella et al. 2022</a></li>
</ul>
<p><strong>The Reference Observing Sequence of the Euclid Wide Survey:</strong></p><ul>
<li>4 dithered pointings per 0.53 deg2 FoV common to VIS & NISP</li>
<li>Simultaneous VIS IE and NISP red grism exposures of 570s</li>
<li>VIS shutter closed (taking biases, flats, & other calibration frames), NISP imaging JE, HE, YE </li>
<li>VIS 108s exp. during the HE exposure in the 1st pointing, to extend PSF dynamic range on relatively bright stars</li>
<li>After each pointing, a dither step is applied & a new grism position is selected (RGS000 & RGS180 at 2 angles each, offset by 4 deg, to allow spectral decontamination).</li>
</ul>
<h1 id="atlas">ATLAS</h1>
<p><strong>ATLAS</strong> is an asteroid impact early warning system developed by the University of Hawaii and funded by NASA. It consists of four telescopes (Hawaii ×2, Chile, South Africa), which automatically scan the whole sky several times every night looking for moving objects. </p><p><strong>ATLAS</strong> will provide a warning time depending on the size of the asteroid – larger asteroids can be detected further from Earth. <strong>ATLAS</strong> will see a small (~20 meter) asteroid several days out, and a 100 meter asteroid several weeks out. A 100 meter asteroid has approximately 10 times the destructive force of the <a href="https://en.wikipedia.org/wiki/2022_Hunga_Tonga_eruption_and_tsunami">2021 Tonga volcanic eruption</a>.</p><p><strong>ATLAS</strong> also processes the survey data to search for stationary transients, which are reported to the<a href="https://wis-tns.weizmann.ac.il/stats-maps"> IAU Transient Name Server</a>. These include supernovae, CVs, stellar outbursts, and fast transients such as GRB afterglows. We also have an agreement with LIGO to search for electromagnetic counterparts to gravitational wave sources. Our colleagues in <a href="https://star.pst.qub.ac.uk/">Queen’s University Belfast</a>, Harvard, and the Space Telescope Science Institute help run these programmes. We are in the top 3 reporting groups worldwide, with more than 300 supernovae candidates found during 2016.

<p>This is the <a href="https://fallingstar.com/">ATLAS</a> forced photometry server, which provides full public access to photometric measurements over the full history of ATLAS survey. After registration, a user can request forced photometry at any position on the sky either for a single position, a list of positions, or moving objects (by MPC name).</p><p>ATLAS is a quadruple 0.5m telescope system with two units in Hawaii (Haleakala and Mauna Loa), and one each in Chile (El Sauce) and South Africa (Sutherland). With the installation of the two southern units, we are robotically surveying the whole sky with a cadence of 1 day between -50 and +50 and 2 days in the polar regions, weather permitting. Two filters are used, cyan and orange (denoted c and o; all mags quoted are in the AB system).</p><p>As described in <a href="https://ui.adsabs.harvard.edu/abs/2018PASP..130f4505T/abstract">Tonry et al. (2018)</a>, ATLAS surveys the whole visible sky. On each night, a sequence of 4 x 30 second exposures are taken, spaced over a period of about one hour to provide identification and orbit constraints for near-earth objects (NEOs). Discovery of NEOs and potentially hazardous objects is the main purpose of ATLAS. However the all-sky, frequent coverage, to o ~ 19.5 makes it treasure trove for time domain science. A full description is on the ATLAS homepage at <a href="https://fallingstar.com/">fallingstar.com</a></p><p>The potential for transient object science and variable star science has been described in <a href="https://ui.adsabs.harvard.edu/abs/2020PASP..132h5002S/abstract">Smith et al. (2020)</a> and <a href="https://ui.adsabs.harvard.edu/abs/2018AJ....156..241H/abstract">Heinze et al. (2018)</a>, respectively. We release all our transient discoveries to the <a href="https://wis-tns.weizmann.ac.il/">IAU’s Transient Name Server</a>.</p><p>A forced photometry means that a point-spread-function is calculated for each image based on high signal to noise stars, and a profile fit is forced at the user’s input coordinates. The forced measurement can be made on either a target image (e.g. for the measurement of flux of a variable star), or on a difference image (e.g. for a lightcurve point for a transient). Data processing and photometry are described in more detail in <a href="https://ui.adsabs.harvard.edu/abs/2018PASP..130f4505T/abstract">Tonry et al. (2018)</a> and <a href="https://ui.adsabs.harvard.edu/abs/2020PASP..132h5002S/abstract">Smith et al. (2020)</a>.</p><h1 id="ztf">ZTF</h1>
