    <description descriptionType="Abstract">&lt;p&gt;This file contains:&lt;/p&gt;

&lt;ul&gt;
	&lt;li&gt;relevant columns from Gaia DR2&lt;/li&gt;
	&lt;li&gt;Pan-STARRS (PS1) photometry (grizy)&lt;/li&gt;
	&lt;li&gt;de-reddened PS1 photometry (g0, r0, etc.)&lt;/li&gt;
	&lt;li&gt;binary masks to apply to select out stars that pass our proper motion and color-magnitude diagram selection (pm_mask, gi_cmd_mask)&lt;/li&gt;
	&lt;li&gt;a binary mask to apply to select out stars in the stream track defined in &lt;a href="https://arxiv.org/abs/1805.00425"&gt;Price-Whelan &amp;amp; Bonaca (2018) &lt;/a&gt;(stream_track_mask)&lt;/li&gt;
	&lt;li&gt;GD-1 positional coordinates (phi1, phi2)&lt;/li&gt;
	&lt;li&gt;Proper motions in the GD-1 coordinate system (pm_phi1_cosphi2, pm_phi2)&lt;/li&gt;
	&lt;li&gt;Proper motions in the GD-1 coordinate system, corrected for solar reflex motion (pm_phi1_cosphi2_no_reflex, pm_phi2_no_reflex)&lt;/li&gt;
&lt;/ul&gt;

&lt;p&gt;To select out probable members of the GD-1 stream in, e.g., Python, use:&lt;/p&gt;

&lt;pre&gt;&lt;code class="language-python"&gt;from astropy.table import Table
tbl = Table.read('gd1-with-masks.fits')
tbl = tbl[tbl['pm_mask'] &amp;amp; tbl['gi_cmd_mask']]&lt;/code&gt;&lt;/pre&gt;

&lt;p&gt;To select out only stars within the stream track identified in &lt;a href="https://arxiv.org/abs/1805.00425"&gt;Price-Whelan &amp;amp; Bonaca (2018)&lt;/a&gt;, do:&lt;/p&gt;

&lt;pre&gt;&lt;code class="language-python"&gt;from astropy.table import Table
tbl = Table.read('gd1-with-masks.fits')
tbl = tbl[tbl['pm_mask'] &amp;amp; tbl['gi_cmd_mask'] &amp;amp; tbl['stream_track_mask']&lt;/code&gt;&lt;/pre&gt;

&lt;pre&gt;
