    <p>To Whom It May Concern, <br>
    </p>
    <p>I am interested in what columns in various datasets stand for.
      Specifically, in the client dataset, what do the following columns
      mean: <br>
    </p>
    <table cellspacing="0" cellpadding="0" border="0" width="384">
      <colgroup><col width="64" span="6"></colgroup><tbody>
        <tr height="20">
          <td style="height:15.0pt;width:48pt" height="20" width="64">transport</td>
          <td style="width:48pt" width="64">version</td>
          <td style="width:48pt" width="64">lower</td>
          <td style="width:48pt" width="64">upper</td>
          <td style="width:48pt" width="64">clients</td>
          <td style="width:48pt" width="64">frac</td>
        </tr>
      </tbody>
    </table>
    <br>
    Also, what do these two columns mean? <br>
    <br>
    <table cellspacing="0" cellpadding="0" border="0" width="128">
      <colgroup><col width="64" span="2"></colgroup><tbody>
        <tr height="20">
          <td style="height:15.0pt;width:48pt" height="20" width="64">percentile</td>
          <td style="width:48pt" width="64">advbw</td>
        </tr>
      </tbody>
    </table>
    <br>
    What do the following columns in the hidserv dataset mean?<br>
    <br>
    <table cellspacing="0" cellpadding="0" border="0" width="320">
      <colgroup><col width="64" span="5"></colgroup><tbody>
        <tr height="20">
          <td style="height:15.0pt;width:48pt" height="20" width="64">wmean</td>
          <td style="width:48pt" width="64">wmedian</td>
          <td style="width:48pt" width="64">wiqm</td>
          <td style="width:48pt" width="64">frac</td>
          <td style="width:48pt" width="64">stats</td>
        </tr>
      </tbody>
    </table>
    <br>
    and these columns in the webstats? <br>
    request_type    platform    channel    locale    incremental   
    count<br>
    <br>
    Lastly, the following columns in the server dataset: <br>
    flag    country    version    platform    ec2bridge    relays   
    bridges<br>
    <br>
    <br>
    Also, how can I find information on when the censorship events took
    place? <br>
    <br>
    Thank you. <br>
    <br>
    Best,<br>
