cds-question@unistra.frearly-type-starseffective-temperatureapparent-magnitudeWith the {Delta}a photometric system, it is possible to study very distant galactic and even extragalactic clusters with a high level of accuracy. The new calibration presented is a powerful extension. Because no a-priori reddening-free photometric parameters are available for the investigated spectral range, we have applied the dereddening calibrations of the Stromgren uvby{beta} system and compared them with extinction models for the Milky Way. We derived an empirical temperature calibration for the {Delta}a photometric system for A-type to mid F-type with a mean of the error for the whole sample of {Delta}T(eff) is 134K which is lower than the value in Paper I (Paunzen et al., 2005, Cat. <J/A+A/444/941>) for hotter stars. No statistically significant effect of the rotational velocity on the precision of the calibration was found.2006A&A...458..293Phttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/458/293CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+AS/117/227 : Dwarf effective temperatures (Alonso+ 1996)J/A+A/391/1039 : Metal-poor A-type stars effective temperature (Kinman+, 2002)J/A+A/411/559 : Effective temperature for 181 F-K dwarfs (Kovtyukh+, 2003)J/ApJ/626/446 : Effective temperature scale of FGK stars (Ramirez+, 2005)J/A+A/444/941 : Effective temperature of B stars (Paunzen+, 2005)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/458/293https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/458/293http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/458/293https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/458/293https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/458/293http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/458/293GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/458/293/table1 (*List of 283 normal type stars used for the calibration)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/458/293/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/458/293/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/458/293/table1?GETtext/xml+votable180.050000true1.7086931-23.107540.0055555555555555566/41 4135 4250 16495 16543 16606 16611 16615 16686 16689 16697 16704 16807 16844 16971 16974 17112 17125 17142 17156 17194 17322 17492 17573 17608 17611 17664 17691 17695 17762 17783 18034 18067 18210 18304 18311 18712 18737 18783 18803-18804 19464 19517 19519 19590 20507 20542 20587 20612 20631-20632 20645 20659 20687-20688 20719 20725 20758 20783 20793 20813 20835 20841 20849 20938 20943 20998 21047 21060 21076 21083 21089 21165 21175 21189 21221 21229 21272 21299 21364 21388 21430 21440 21458 21462 21477 21506 21526 21536 21538 21543 21615 21729 21733 21946 21993 22034 22077 22130 22154 22171 22198 22201 22230 22285 22289 22315 22329 22343 22410 22434 22436 22576 22594 22596 22655 22691 22704 22805 22813 22874 22917 22919-22920 22925 22963 23007 23261 23323 23438 23443-23444 23446 23552 23557 23592 23599 23632 23655 23701 27269 27282 32797 32914 32921 33013 33100 33193 33273 33351 33361 33396 33430 33496 33519 33547 33584 33694 33796 33800 33905 33920 34120 34164 34257 34278 34306 34347 34394 34458 34536 34538 34589 34624 34685 34724 34745 34785 34789 34823 34908 34941 34997 35061 35165 35293 35354 35391 35440 35447 35483 35529 35603 35635 35706 35723 35849 35900 35940 35954 35967 35973 35999 36036 36047 36079 36130 36177 36245 36345 36372 36391 36514 36575 36691 36758 36770 36850-36851 36874 37003 37012 37055 37090 37101 37407 37445 37548 37616 37673 37691 37775 37810 37816 37832 38941 38950 38958 39033 39037 39204 39261 39348 39364 39394 39491 39502 39519 39555 39579 39593 39607 39611 39640 39692 39702 39732 39808 39860 39885 39898 39918 39922 39976 40124 40477 40652 40699 40788 45144 45394 46084 46131 46181 46430 46538 46921 46935https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/458/293?format=asciiOpticaldefaultJ/A+A/458/293/table1*List of 283 normal type stars used for the calibrationSpTypeMK spectral typesrc.spTypecharHDHD number (Cat.
