cds-question@unistra.fropen-star-clustersinfrared-photometryvisible-astronomybroad-band-photometryh-alpha-photometryyoung-stellar-objectsWe present deep wide-field optical CCD photometry and mid-infrared Spitzer/IRAC and MIPS 24{mu}m data for about 100000 stars in the young open cluster IC 1805. The members of IC 1805 were selected from their location in the various color-color and color-magnitude diagrams, and the presence of H{alpha} emission, mid-infrared excess emission, and X-ray emission. The reddening law toward IC 1805 is nearly normal (R_V_=3.05+/-0.06). However, the distance modulus of the cluster is estimated to be 11.9+/-0.2mag (d=2.4+/-0.2kpc) from the reddening-free color-magnitude diagrams, which is larger than the distance to the nearby massive star-forming region W3(OH) measured from the radio VLBA astrometry. We also determined the age of IC 1805 ({tau}_MSTO_=3.5Myr). In addition, we critically compared the age and mass scale from two pre-main-sequence evolution models. The initial mass function with a Salpeter-type slope of {Gamma}=-1.3+/-0.2 was obtained and the total mass of IC 1805 was estimated to be about 2700+/-200M_{sun}_. Finally, we found our distance determination to be statistically consistent with the Tycho-Gaia Astrometric Solution Data Release 1, within the errors. The proper motion of the B-type stars shows an elongated distribution along the Galactic plane, which could be explained by some of the B-type stars being formed in small clouds dispersed by previous episodes of star formation or supernova explosions.2017ApJS..230....3Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJS/230/3CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toII/246 : 2MASS All-Sky Catalog of Point Sources (Cutri+ 2003)VII/233 : The 2MASS Extended sources (IPAC/UMass, 2003-2006)III/274 : Galactic O-Star Spectroscopic Survey (Sota+, 2014)J/ApJS/2/389 : Observations of O and B stars (Hiltner, 1956)J/ApJ/454/151 : OB Associations of the Northern Milky Way (Massey+ 1995)J/AJ/114/2644 : UBVRIHa photometry of NGC2264 (Sung+, 1997)J/AJ/123/2597 : H{alpha} stars and HH objects near BRCs (Ogura+, 2002)J/AJ/127/1014 : CCD UBVRIHa photometry in NGC 3603 (Sung+, 2004)J/AJ/128/1684 : NGC 2264: VRIH{alpha} photometry (Sung+, 2004)J/ApJ/639/1069 : Radial velocities in the Cas OB6 association (Hillwig+, 2006)J/AJ/133/1092 : vsini of B0-B3 stars in 7 young clusters (Wolff+, 2007)J/AJ/133/1795 : Globulettes in four HII regions (Gahm+, 2007)J/AJ/135/441 : VRIH{alpha} photometry in NGC 2264 (Sung+, 2008)J/AJ/138/1116 : A Spitzer view of NGC 2264 (Sung+, 2009)J/AJ/141/23 : HI holes in THINGS galaxies (Bagetakos+, 2011)J/ApJ/726/19 : Intermediate-mass stars in IC 1805 (Wolff+, 2011)J/other/Sci/337.444 : RV curves of Galactic massive O stars (Sana+, 2012)J/A+A/553/A24 : Models for rotating stars (Georgy+, 2013)J/A+A/554/A3 : Vilnius photometry of IC1805 stars (Straizys+, 2013)J/AJ/145/37 : UBVI and H{alpha} CCD photometry of NGC 6231 (Sung+, 2013)J/ApJS/213/1 : The MSFRs Omnibus X-ray Catalog (MOXC) (Townsley+, 2014)J/ApJ/822/49 : Candidate YSOs in AFGL 333 with NEWFIRM+Spitzer (Jose+, 2016)J/A+A/594/A82 : XMM sources in IC 1805 (Rauw+, 2016)http://sha.ipac.caltech.edu/applications/Spitzer/SHA/ : Spitzer archivehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJS/230/3https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJS/230/3http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJS/230/3https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJS/230/3https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJS/230/3http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJS/230/3GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJS/230/3/table2 (Photometric data from CFHT observations)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJS/230/3/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJS/230/3/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJS/230/3/table2?GETtext/xml+votable180.050000true37.43812561.51480560.005555555555555556Cone search capability for table J/ApJS/230/3/table5 (Photometric data from the Maidanak AZT-22 1.5m telescope and SITe 2000x800 CCD)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJS/230/3/table5?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJS/230/3/table5?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJS/230/3/table5?GETtext/xml+votable180.050000true37.490416761.27638890.005555555555555556Cone search capability for table J/ApJS/230/3/table6 (Photometric data from the Maidanak AZT-22 1.5m telescope and Fairchild 486 CCD (SNUCam))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJS/230/3/table6?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJS/230/3/table6?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJS/230/3/table6?GETtext/xml+votable180.050000true37.92112561.3850.005555555555555556Cone search capability for table J/ApJS/230/3/table8 (Catalog of Spitzer Space Telescope IRAC and MIPS 24um sources)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJS/230/3/table8?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJS/230/3/table8?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJS/230/3/table8?GETtext/xml+votable180.050000true36.80387562.35083330.0055555555555555566/3305 3306 3307 3310 3649 36526.772611666688002e-21 4.0411735702351523e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJS/230/3?format=asciiOpticalInfrareddefaultJ/ApJS/230/3/table2Photometric data from CFHT observationsrecnoRecord number assigned by the VizieR team.
