cds-question@unistra.frsupernovaephotometryWe present BVRI light curves of 165 Type Ia supernovae (SNe Ia) from the Lick Observatory Supernova Search follow-up photometry program from 1998 through 2008. Our light curves are typically well sampled (cadence of 3-4 days) with an average of 21 photometry epochs. We describe our monitoring campaign and the photometry reduction pipeline that we have developed. Comparing our data set to that of Hicken et al., with which we have 69 overlapping supernovae (SNe), we find that as an ensemble the photometry is consistent, with only small overall systematic differences, although individual SNe may differ by as much as 0.1 mag, and occasionally even more. Such disagreement in specific cases can have significant implications for combining future large data sets. We present an analysis of our light curves which includes template fits of light-curve shape parameters useful for calibrating SNe Ia as distance indicators. Assuming the B-V color of SNe Ia at 35 days past maximum light can be presented as the convolution of an intrinsic Gaussian component and a decaying exponential attributed to host-galaxy reddening, we derive an intrinsic scatter of {sigma}=0.076+/-0.019mag, consistent with the Lira-Phillips law. This is the first of two papers, the second of which will present a cosmological analysis of the data presented herein.2010ApJS..190..418Ghttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJS/190/418CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/AJ/112/2408 : Light Curves of 29 SNe (Hamuy+ 1996)J/MNRAS/389/1577 : UBVRI absolute magnitudes of Type Ia SNe (Takanashi+, 2008)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJS/190/418https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJS/190/418http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJS/190/418https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJS/190/418https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJS/190/418http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJS/190/418GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJS/190/418/sne (SNe positions from Simbad)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJS/190/418/sne?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJS/190/418/sne?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJS/190/418/sne?GETtext/xml+votable180.050000true12.0287527.6244440.005555555555555556Cone search capability for table J/ApJS/190/418/table7 (Comparison stars (165 SNe))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJS/190/418/table7?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJS/190/418/table7?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJS/190/418/table7?GETtext/xml+votable180.050000true12.026458327.65088890.0055555555555555566/626 928 1700 1796 2142 2169 2227 2232 2251 2254 2265 2347 2379 2409 2412 2473 3393 4401 4416 4447 4577 4684 4719 5006 5680 5995 6062 6101 6114 6115 6178 6962 7044 7104 7123 7240 7241 7369 7488 7747 8403 8526 8556 8927 9136 9287 9449 9560 9640 9751 10144 10203 10379 10397 10398 10428 10429 10563 10650 10788 10789 11273 11496 12367 12453 12455 13313 13347 13350 13397 13399 13427 13459 13504 13505 13514 13536 14009 14733 14834 14882 15056 15548 15550 16852 17197 17239 17340 17401 17500 17614 17670 17761 17817 18206 18324 18325 18394 18735 18753 18895 19051 19062 19094 19241 19243 19283 19298 19387 19515 19560 19848 19958 20014 20090 20140 20283 20370 21136 21138 21300 22826 23013 23828 23916 24920 24922 25079 25344 25491 25494 25615 25769 25889 25960 26117 26128 26265 26268 26270 26392 26500 26563 27172 27174 27426 27761 27945 28033 28035 28075 28089 28249 28353 28356 28368 28417 28453 28464 28593 28595 30041 30044 31218 31227 31230 31313 31628 32130 32136 32561 32563 32569 32572 32591 32602 32620 36045 36287 36805 39677 39679 40252 40379 44915 44921 45041 48075 48078 48097 48665 48898https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJS/190/418?format=asciiOpticaldefaultJ/ApJS/190/418/sneSNe positions from SimbadrecnoRecord number assigned by the VizieR team.
