We present a new pipeline, DIAmante, developed to extract optimized, multisector photometry from TESS FFIs and a classifier, based on the Random Forest technique, trained to discriminate plausible transiting planetary candidates from common false positives. A new statistical model was developed to provide the probability of correct identification of the source of variability. We restricted the planet search to the stars located in the least crowded regions of the sky and identified 396 transiting planetary candidates among which 252 are new detections. The candidates' radius distribution ranges between 1R_{Earth}_ and 2.6R_J_ with median value of 1R_J_ and the period distribution ranges between 0.25 and 105d with median value of 3.8d. The sample contains four long period candidates (P>50d), one of which is new, and 64 candidates with periods between 10 and 50d (42 new ones). In the small planet radius domain (4R<R_{Earth}_), we found 39 candidates among which 15 are new detections. Additionally, we present 15 single transit events (14 new ones), a new candidate multiplanetary system, and a novel candidate around a known TOI. By using Gaia dynamical constraints, we found that 70 objects show evidence of binarity. We release a catalogue of the objects we analysed and the corresponding light curves and diagnostic figures through the MAST and ExoFOP portals.2020MNRAS.498.1726Mhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/498/1726CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toI/345 : Gaia DR2 (Gaia Collaboration, 2018)I/347 : Distances to 1.33 billion stars in Gaia DR2 (Bailer-Jones+, 2018)IV/39 : TESS Input Catalog version 8.2 (TIC v8.2) (Paegert+, 2021)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/498/1726https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/498/1726http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/498/1726https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/498/1726https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/498/1726http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/498/1726GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/498/1726/table7 (Content of the catalogue released with this work)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/498/1726/table7?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/498/1726/table7?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/498/1726/table7?GETtext/xml+votable180.050000true90.08601210580061.7922046327830.0055555555555555566/4099 4145 4161 4163 4238 4619 16405 16438 16472 16633 16660 16742 16774 16788 16840 16947 17002 17162 17186 17198 17202 17240 17300 17430 17550 17591 17605 17705 17753 17763-17764 17819 17832 17865 17995 18437 18452 20548 20558 20565-20566 20609 20613 20667 20686 20690 20707 20714 20869 20996 21011 21026 21039 21045 21093 21099 21108 21137 21206 21252 21254 21265 21293-21294 21308 21357 21431 21433 21447 21477 21482 21485 21630 21820 21917 21975 21989 22001 22369 22396 22405 22467 22505 22554 22589 22661 22678 22816 22834 22886 22890 22892 22896 22904 22963 22997 23093 23178 23186 23214 23422 23485 23555 23584 23600 23683 24093 24105 24591 24631 24697 24766 24769 24887 24948 25048 25095 25122 25132 25145 25153 25158 25194 25283 25408 25427 25492 25524 25604 26633 26759 26771 26787 26918 26920 27056 32821 32862 32870 32912-32913 32964-32965 32980 33001 33145 33157 33194 33200 33221 33279 33393 33404 33473 33494 33580 33592 33600 33696 33719 33723 33750 33821 33840 33854 33875 33884 33890 33892 33898 33914 33919 33921 33972-33973 34002 34020 34024 34068 34089 34113 34120-34121 34171 34194-34195 34268 34276 34286 34295 34332 34423 34468 34471 34480 34516 34561 34566 34581 34694 34716 34722 34751 34812 34847 34898 34943 34960 35011 35155 35160 35275 35301-35302 35350 35456 35486 35536 35624 35868 35879 35938 35993 36067 36086 36116 36142 36165 36191 36196-36197 36248 36416 36497 36576 36640 36714 36978 37026 37113 37376 37391 37411 37426 37449 37453 37458 37484-37485 37519 37528 37548 37551 37579 37595 37611 37629 37839 37850 38207 38246 38340 38351 38597 38646 38883 38904 38946 38979 38982 38997 39016 39022 39026 39042 39075 39077 39116 39136 39147 39425 39428 39438 39487 39490 39506 39512 39525 39558 39580 39599 39611 39632 39651-39652 39657 39679 40186 40189 40207 40222 40230 40347 40361 40382 40428 40573 40714 40760 40810 40820 40855 40862 41218 41224 41282 41300 43643 43668 43679 43696-43698 43703 43745 43775 43786 43822 43916-43917 43960 44099 44166 44223 44323 44561 45218 45638 45706 45737 45775 45855 45925 45928 45932 46002 46092 46109 46124 46135 46195 46242 46316 46333 46338 46421 46429 46436-46437 46629 46665 46693 46710 46738 46778 46780 46872 46987 46993 47031 47036 47110 47154 47193 47327 47362 48138 48159 48175 48184 48243 48279 48327 48414-48415 48490 48521https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/498/1726?format=asciiOpticaldefaultJ/MNRAS/498/1726/table7Content of the catalogue released with this workNtrNumber of transitsmeta.numberintSimbadNameSimbad column added by the CDSmeta.idcharnullablerhoStellar density from TICg.cm**-3phys.densityfloate_rhoError on rhog.cm**-3stat.errorfloatcontratioContamination ratio from TIC%meta.numberfloatTmagTESS magnitude from TICphot.mag;em.optfloatrecnoRecord number assigned by the VizieR team.
