cds-question@unistra.frsurveyssupernovaevisible-astronomysloan-photometryThe Foundation Supernova Survey aims to provide a large, high-fidelity, homogeneous, and precisely calibrated low-redshift Type Ia supernova (SN Ia) sample for cosmology. The calibration of the current low-redshift SN sample is the largest component of systematic uncertainties for SN cosmology, and new data are necessary to make progress. We present the motivation, survey design, observation strategy, implementation, and first results for the Foundation Supernova Survey. We are using the Pan-STARRS telescope to obtain photometry for up to 800 SNe Ia at z<~0.1. This strategy has several unique advantages: (1) the Pan-STARRS system is a superbly calibrated telescopic system, (2) Pan-STARRS has observed 3/4 of the sky in grizyP1 making future template observations unnecessary, (3) we have a well-tested data-reduction pipeline, and (4) we have observed ~3000 high-redshift SNe Ia on this system. Here, we present our initial sample of 225 SN Ia grizP1 light curves, of which 180 pass all criteria for inclusion in a cosmological sample. The Foundation Supernova Survey already contains more cosmologically useful SNe Ia than all other published low-redshift SN Ia samples combined. We expect that the systematic uncertainties for the Foundation Supernova Sample will be two to three times smaller than other low-redshift samples. We find that our cosmologically useful sample has an intrinsic scatter of 0.111mag, smaller than other low-redshift samples. We perform detailed simulations showing that simply replacing the current low-redshift SN Ia sample with an equally sized Foundation sample will improve the precision on the dark energy equation-of-state parameter by 35 per cent, and the dark energy figure of merit by 72 per cent.2018MNRAS.475..193Fhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/475/193CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toB/sn : Asiago Supernova Catalogue (Barbon et al., 1999-)II/33 : Sloan Digital Sky Survey-II Supernova Survey (Sako+, 2018)II/366 : ASAS-SN catalog of variable stars (Jayasinghe+, 2018-2020)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/475/193https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/475/193http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/475/193https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/475/193https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/475/193http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/475/193GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/475/193/listlc (List of supernovae with light curves in table2)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/475/193/listlc?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/475/193/listlc?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/475/193/listlc?GETtext/xml+votable180.050000true108.05979177.23977780.0055555555555555566/236 524 650 1012 2138 2214 2417 3108 4532 4562 4825 4833 5024 5362 5610 5781 5852 6219 7180 7325 7622-7623 7975 8247 8276 8465 8481 8731 9229 9468 9484 9565 9601 9806 9881 9939 10326 10380 10533 10556 10643 10833 11337 11588 12471 12493 13550 13564 14962 16999 17146 17185 17282 17329 17360 17625 17689 18120 18212 18596 18802 18842 18939 19671 19686 20288 21159 21263-21264 21270 21783 22406 22704 23027 23060 23233 24734 24823 24898 25855 25986 25996 26060 26102 26402 26454 26458 26499 27084 27201 27245 27561 27808 27864 27904 27926 28363 28544 28554 30100 31881 32162 32275 32492 32522 36623 36798 40384 40435 44022 44511 44710 44971 45016 48471 48481 48667https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/475/193?format=asciiOpticaldefaultJ/MNRAS/475/193/listlcList of supernovae with light curves in table2recnoRecord number assigned by the VizieR team.
