cds-question@unistra.frradio-galaxiesh-i-line-emissionradio-astronomyWe present Arecibo neutral hydrogen data on a sample of optically selected dwarf galaxies. The sample ranges in H I mass from 10^6^ to 5x10^9^M_{sun}_, with a mean of 7.9x10^8^M_{sun}_. Using estimated H I radii, the H I surface densities range from 0.6 to 20M_{sun}_/pc^2^, all well below the critical threshold for star formation (Kennicutt, 1998ApJ...498..541K). M_HI_/L values of the LSB dwarfs range from 0.3 to 12 with a mean value of 2.0. Dynamical masses, calculated from the H I profile widths, range from 10^8^ to 10^11^M_{sun}_. There is a strong correlation between optical luminosity and dynamical mass for LSB dwarfs implying that the dark matter (whether baryonic or nonbaryonic) follows the detectable baryonic matter.2000ApJS..131...47Ehttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJS/131/47CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJS/131/47https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJS/131/47http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJS/131/47https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJS/131/47https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJS/131/47http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJS/131/47GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJS/131/47/table1 (LSB Dwarf Galaxy Sample)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJS/131/47/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJS/131/47/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJS/131/47/table1?GETtext/xml+votable180.050000true0.73432129.5841920.0055555555555555565/6894 6/523 526 2063 2079 2096 2100 2104 2107 2122 2181 4258 4265 4271 4301 4302 4303 4313 4337 4339 4341 4342 4343 4344 4345 4348 4357 4368 4373 4375 4380 4381 4383 4405 4411 4416 4418 4420 4424 4427 4444 4447 4448 4479 4494 4496 4507 4508 4511 4512 4514 4517 4522 4523 4524 4527 4534 4539 4546 4552 4554 4614 4617 4646 4647 4648 4649 4650 4655 4689 4691 4695 4701 4720 4758 4761 4776 4807 4823 4829 4864 4866 4876 5128 5129 5152 5159 6153 8327 8334 8337 8343 8371 8373 8375 8376 8379 8382 8418 8428 8429 8431 8518 8519 8537 8541 8548 8557 8563 8568 8575 8605 8607 8612 8625 8639 8680 8706 8779 8829 8838 8841 8864 8866 8871 8873 8918 8919 8992 9002 9006 9026 9029 9036 9096 9097 9100 9256 9345 9349 10242 10250 10279 10280 10370 10377 10380 13380 13383 17919 18167 18175 18256 18258 18267 18289 18292 18293 18297 18300 18375 18378 18381 18382 18383 18394 18404 18416 18425 18426 18427 18934 18935 19489 19491 19498 19502 19541 19545 19585 19588 19589 19590 19625 19626 19627 19630 19642 19646 19707 19708 19709 19710 19731 19748 19769 19818 19827 19833 19851 19852 19873 19879 19882 19889 19890 19899 19900 19907 19915 19920 19923 19936 19942 19954 19958 19964 19970 19973 19974 19976 19977 20187 20195 20203 20215 20218 20219 20225 20228 20240 20241 20277 20281 20299 20320 20321 20326 20327 20328 20329 20330 20381 20416 20420 20426 22288 22292 22332 22345 22389 22391 22465 22522 22527 23901 23903 26110 26439 26445 26448 26451 26454 26456 26457 26460 26462 26485 26491 26494 26554 26555 26614 26615 26621 27383 27508 27510 27518 27554 27556 27564 27566 27568 27580 27624 27626 27627 27898 27899 27911 27926 27929 27932 27934 27965 27974 27980 27982 27986 27988 27989 27994 27996 27998 28001 28003 28025 28072 28100 28101 28169 28193 28201 28202 28210 28213 28215 28221 28233 28239 28243 28252 28257 28265 28270 28272 28275 28290 28294 28330 28333 28384 28418 31721 31726 31740https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJS/131/47?format=asciiRadiodefaultJ/ApJS/131/47/table1LSB Dwarf Galaxy SampleVWidth?
