cds-question@unistra.frplanetary-nebulaestellar-distancevisible-astronomytrigonometric-parallaxPlanetary Nebula distance scales often suffer for model dependent solutions. Model independent trigonometric parallaxes have been rare. Space based trigonometric parallaxes are now available for a larger sample using the second data release of Gaia. We aim to derive a high quality approach for selection criteria of trigonometric parallaxes for planetary nebulae and discuss possible caveats and restrictions in the use of this data release. A few hundred sources from previous distance scale surveys were manually cross identified with data from the second Gaia data release (DR2) as coordinate based matching does not work reliable. The data are compared with the results of previous distance scales and to the results of a recent similar study, which was using the first data release Gaia DR1. While the few available previous ground based and HST trigonometric parallaxes match perfectly to the new data sets, older statistical distance scales, reaching larger distances, do show small systematic differences. Restricting to those central stars, were photometric colors of Gaia show a negligible contamination by the surrounding nebula, the difference is negligible for radio flux based statistical distances, while those derived from H-alpha surface brightness still show minor differences. The DR2 study significantly improves the previous recalibration of the statistical distance scales using DR1/TGAS.2018A&A...616L...2Khttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/616/L2CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toI/345 : Gaia DR2 (Gaia Collaboration, 2018)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/616/L2https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/616/L2http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/616/L2https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/616/L2https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/616/L2http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/616/L2GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/616/L2/tablea (Matched PN G vs Gaia DR2 identifications)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/616/L2/tablea?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/616/L2/tablea?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/616/L2/tablea?GETtext/xml+votable180.050000true250.97408516333002-18.9533300501820.0055555555555555565/7195 6/361 1111 1200 1223 1238 1338 1399 1455 1552 1562 2395 2558 2883 2979 3020 3128 3152 3199 3291 3324 3332 3353 3365 3586 3637 3659 3732 3819 4244 4690 5996 6146 6292 7090 7134 7392 9233 9276 9806 11605 12222 12515 12577 12812 12852 12857 12907 12944 12960 12971 12983 12994 13149 13676 13796 13814 13968 14011 14140 14198 14214 14226 14245 14258 14279 14338-14339 14344 14360 14362 14415 14443 14482 14491 14592 14596 14602 14608 14719 14796 14827 14853 15145 15172 15351 15377 15379 15425 15435 15437 15472 15552 15561 15621 15639 15721 15750 15752 16243 16886 19741 20776 20951 21215 21218 21523 21651 21818 21948 22053 22093 22166 22279-22280 22441 22478 22660 23389 23576 23658 23663 23688 23704 23734 24361 24379 24862 25008 27192 28703 28711 28716 28718 28721-28723 28728 28756 28772 28777-28778 28797 28805 28821 28823 28840 28844 28849 28854 28860 28870 28881 28892 28917 28922 28943 28977 28986 28991 29037 29057 29086-29087 29092 29094 29096 29104 29109 29130 29147 29160 29182 29193 29200 29213 29236 29257 29266-29267 29317 29326 29350 29393 29427 29451 29470 29520 29527 29566 29654 29718 29743 29852 29859 29868 29886 29899 30110 30135 30214 30226-30227 30266 30276 30278 30282 30288 30319 30328 30340 30349 30385 30390 30397 30403 30435 30504-30505 30511 30518 30527 30615 30621 30637 30657-30658 30675 30684 30686 30699 30803 31026 31670 31775 31847 31895 32001 32005 32042 32066 32070-32071 32092 32101 32124 32193 32372 32581 36130 36938 37110 37191 37212 37316 37322-37323 37337 37661 37701 37731 37734-37735 37915 37959 38001 38031 38075 38364 38433 38475 38512 38563 38763 39029 39198 39709 39801 39822 39935 40070 40279 40433 40510 40571 40577 41174 41186 41268 41336 41371 41434 41437 41439 41442 41448 41470 41495 41574 41576 41580 41596 41640 41663-41664 41674 41713 41732 41754 41768 41789 41793 41799 41803 41826 41831-41832 41842 41849 41886 41903 42088 42094 42099 42125 42139 42147 42160 42168 42180 42254 42267 42312-42313 42396 42437 42454 42478-42479 42505 42579 42632 42664 42709 42711 42753 42792 42795 42811 42835 42893 43012 43268 43296 43360 44416 44703 44707 45243 46712 47100 47627 47663 47711 47921 48775-48776 48951 490831.9867573869263685e-19 3.916500758235022e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/616/L2?format=asciiOpticaldefaultJ/A+A/616/L2/tableaMatched PN G vs Gaia DR2 identificationsrecnoRecord number assigned by the VizieR team.
