The catalogue consists of 181 IPHAS-selected new classical Be stars, in addition to 66 objects that we studied in our previous work more closely, and three stars identified as classical Be stars in earlier work. This study more than doubles the number known in the region. Photometry spanning 0.6-5um, spectral types, and interstellar reddenings are given for each object. The spectral types were determined from low-resolution spectra ({lambda}/{Delta}_{lambda}~800-2000), to a precision of 1-3 subtypes. The interstellar reddenings are derived from the (r-i) colour, using a method that corrects for circumstellar disc emission. The colour excesses obtained range from E(B-V)=0.3 up to 1.6 a distribution that modestly extends the range reported in the literature for Perseus-Arm open clusters. For around half the sample, the reddenings obtained are compatible with measures of the total sightline Galactic extinction. Many of these are likely to lie well beyond the Perseus Arm.2015MNRAS.446..274Rhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/446/274CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toII/321 : IPHAS DR2 Source Catalogue (Barentsen+, 2014)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/446/274https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/446/274http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/446/274https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/446/274https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/446/274http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/446/274GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/446/274/catalog (Catalogue of the Be stars: photometric data (table A1), spectral types and interstellar reddenings (table B1))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/446/274/catalog?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/446/274/catalog?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/446/274/catalog?GETtext/xml+votable180.050000true6.173833364.36052780.0055555555555555565/819 826-828 903 909 913 920 930-931 6/3039 3056 3059-3060 3062-3063 3263 3270 3275 3289-3291 3294 3297 3299-3302 3320 3322 3606-3607 3611 3623 3631-3632 3635 3640 3642-3644 3646-3648 3650-3651 3656 3658-3662 3664 3666 3684 3686 3688 3713 3715-3718 3728-3729 3732-3734 3748-3749 37515.3455714667354156e-20 3.6117181231747793e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/446/274?format=asciiOpticalInfrareddefaultJ/MNRAS/446/274/catalogCatalogue of the Be stars: photometric data (table A1), spectral types and interstellar reddenings (table B1)e_i-W1?
