    <dct:description>&lt;p&gt;This dataset contains a recording of X-band telemetry downlink from the Lucy spacecraft done on 2021-10-17,about 24 hours after launch. The recording was done at Allen Telescope Array using antenna 2e in dual XY (linear) polarization.&lt;/p&gt; &lt;p&gt;The hardware configuration was as follows: antenna 2e was connected to RFCB LO d, which was tuned to a frequency of 8445.6 MHz and used an output IF of 512 MHz. A USRP N321 was connected to the IF output of the RFCB and digitized both polarizations. The USRP used external 10 MHz reference and PPS coming from the observatory distribution system. The IQ&amp;nbsp; sample rate of the USRP was 1.92 Msps and a GNU Radio flowgraph was used to record IQ data to disk.&lt;/p&gt; &lt;p&gt;The GNU Radio flowgraph stored the IQ data for each channel as 16-bin integers in the &lt;a href="https://wiki.gnuradio.org/index.php/Metadata_Information"&gt;GNU Radio metatata file format&lt;/a&gt;, with detached headers. The complete recording was split in two parts to keep the file size below 50 GB. After this, the data was converted to &lt;a href="https://github.com/gnuradio/SigMF"&gt;SigMF&lt;/a&gt; format.&lt;/p&gt; &lt;p&gt;This dataset contains part 1, polarization X. These are the datasets in this collection:&lt;/p&gt; &lt;ul&gt; &lt;li&gt;&lt;a href="https://zenodo.org/record/5577180"&gt;Lucy recording with Allen Telescope Array on 2021-10-17: part 1/2, polarization X&lt;/a&gt;&lt;/li&gt; &lt;li&gt;&lt;a href="https://zenodo.org/record/5579165"&gt;Lucy recording with Allen Telescope Array on 2021-10-17: part 1/2, polarization Y&lt;/a&gt;&lt;/li&gt; &lt;li&gt;&lt;a href="https://zenodo.org/record/5582218"&gt;Lucy recording with Allen Telescope Array on 2021-10-17: part 2/2, polarization X&lt;/a&gt;&lt;/li&gt; &lt;li&gt;&lt;a href="https://zenodo.org/record/5585389"&gt;Lucy recording with Allen Telescope Array on 2021-10-17: part 2/2, polarization Y&lt;/a&gt;&lt;/li&gt; &lt;/ul&gt;</dct:description>
