To generate this sample, the team applies a UV-IR color selection criteria to photometric data from the Ultraviolet GAlactic Plane Survey (UVGAPS) as part of GALEX-CAUSE, the Million Quasars Catalog, Gaia DR2, and Pan-STARRS DR1. 165 of these 305 candidate UV-bright AGN (54%) have published  spectroscopic redshifts from 45 different surveys, confirming them as AGN. The team further obtained low-dispersion, optical, longslit spectra with the APO 3.5-m, MDM 2.4-m, and MDM 1.3-m telescopes for 84 of the candidates, and confirm 86% (N = 72) as AGN, generally with z < 0.6. These sources fill a gap in the Galactic latitude coverage of the available samples of known UV-bright QSO background probes.   Along with a description of the confirmed QSO properties, the team provides the fully-reduced, flux and wavelength-calibrated spectra of 84 low-latitude QSOs through the Mikulski Archive for Space Telescopes.  Future HST/COS spectroscopy of these low-Galactic-latitude QSOs has the potential to transform our view of the Milky Way and Local Group circumgalactic medium. <br />  </p> <script>hljs.initHighlightingOnLoad();</script> </div></section><section id="section-778b4f0d-d211-4ffe-b495-0d9d3ed1eb73" data-name="section-data-products" class="section-row light-background-stsci-light-grey" > <div class="component-block container-fluid"> <div class="row"> <div class="section-header col-xs-12 text-center"> <h2 id="h2-778b4f0d-d211-4ffe-b495-0d9d3ed1eb73" data-name="h2-data-products" class="section-header__title" data-include-in-navigation="true"> Data Products</h2> <p>The full PQS collection consists of 1 summary catalog and 82 spectra files. </p> </div> </div> </div> <div class="component-block container-fluid"> <p data-name=""><span style="font-size: 1rem;">Data file types:</span></p> <table class="sortable-table filterable-table js-data-table display" data-b-sort="true" data-module-dynamic="data-table" data-order="[]" data-searching="true" style="width:80%;"> <thead> </thead> <tbody> <tr> <td style="width: 124px; text-align: right;"><strong>_1dspec.fits</strong></td> <td style="width: 576px;"><span style="font-size: 1rem;">The 1D reduced, wavelength and flux-calibrated spectra are provided for each PQS target we observed with the APO 3.5-m, the MDM 2.4-m, or the MDM 1.3-m.
