cds-question@unistra.frmilky-way-galaxyinterstellar-mediumh-i-line-emissionWe analyse the all-sky Leiden/Argentina/Bonn HI survey, where we identify shells belonging to the Milky Way. We used an identification method based on the search of continuous regions of a low brightness temperature that are compatible with given properties of HI shells. We found 333 shells in the whole Galaxy. The size distribution of shells in the outer Galaxy is fitted by a power law with the coefficient of 2.6 corresponding to the index 1.8 in the distribution of energy sources. Their surface density decreases exponentially with a scale length of 2.8kpc. The surface density of shells with radii >100pc in the solar neighbourhood is around 4 per kpc^2^ and the 2D porosity is around 0.7.2013A&A...550A..23Ehttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/550/A23CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/550/A23https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/550/A23http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/550/A23https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/550/A23https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/550/A23http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/550/A23GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/550/A23/tablea1 (Observed properties of HI shells)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/550/A23/tablea1?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/550/A23/tablea1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/550/A23/tablea1?GETtext/xml+votable180.050000true246.9405-13.75110.0055555555555555566/239 281 802 1118 1228 1288 1436 1515 1651 1714 1776 1799 1913 2829 2880 2921 2961 3003 3019 3085 3092 3150 3191 3210 3229 3234 3327 3390 3408 3498 3504 3555 3569 3640 3685 3688 3698 3753 3759 3786 3790 3837 3893 3899 3990 4040 6281 6562 6759 6841 6882 6950 7591 7850 7985 12414 12974 13037 13050 13055 13203 13210 13259 13268 13283 13528 13604 13729 13893 13917 13972 14011 14017 14027 14048 14065 14092 14132 14135 14158 14190 14233 14243 14257 14270 14304 14316 14318 14357 14403 14416 14434 14449 14466 14473 14576 14600 14620 14639 14652 14708 14715 14732 14747 14829 14860 15361 15375 15377 15386 15408 15413 15444 15463 15543 15593 15637 15648 15652 15676 15679 15689 15752 15802 15810 15922 16177 16262 18273 18406 20891 20939 21301 21332 21339 21438 21478 21555 21645 21670 21672 21706 21733 22049 22065 22089 22114 22169 22172 22240 22319 22437 22681 22856 22895 22982 23025 23150 23209 23289 23526 23557 23564 23624 23699 23713 23740 23777 23789 23827 23832 23967 23971 24036 24192 24209 24258 24286 24506 24508 24540 24546 24765 25156 26524 27031 27143 27590 28787 28894 28970 29218 29309 29386 29429 29442 29447 29561 29631 29637 29880 30073 30228 30243 30250 30255 30290 30311 30340 30531 30542 30639 30658 30670 30672 30692 30768 30790 30965 31782 31821 32056 32061 32169 32402 32513 32889 33175 34813 37246 37337 37345 37369 37667 37671 37697 37714 37726 37734 37777 37791 37797 37803 37809 37829 37836 37859 37862 37866-37867 37874 37904 37920-37921 37932 38037 38071 38274 38413 38444 38451 38468 38509 38555 38563 38586 38918 39032 39191 39202 39229 39232 39245 39263 39276 39287 39311 39323 39327 39343 39384 39401 39409 39422 39576 39597 39665 39699 39786 39791 39826 39921 39988 40070 40630 41503 41628 41639 41644 41654 41666 41669 41735 41737 41746 41748 41878 41915 41940 41949 42042 42100 42117 42126 42142 42236 42297 42301 42356 42374 42426 42478 42519 42537 42647 42856 42868 43071 45210 47537 47594 49006 49119https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/550/A23?format=asciiRadiodefaultJ/A+A/550/A23/tablea1Observed properties of HI shellsrecnoRecord number assigned by the VizieR team.
