The resulting spectra of 30 meteorites are compared with selected spectra from the NASA Planetary Data System meteorite spectra database.

The motivation is to improve the link between asteroid spectral observations and meteorite spectral measurements.&#8221;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Antti Penttil\u00e4, Julia Martikainen, Maria Gritsevich, Karri Muinonen Journal of Quantitative Spectroscopy and Radiative Transfer, Volume 206, February 2018, Pages 189-197 LINK Update (16 February 2018): PDF (OPEN ACCESS) &#8220;Highlights \u2022 Meteorite samples are measured&#8230;<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[77,8],"tags":[1854,197,4288],"_links":{"self":[{"href":"https:\/\/karmaka.de\/index.php?rest_route=\/wp\/v2\/posts\/13923"}],"collection":[{"href":"https:\/\/karmaka.de\/index.php?rest_route=\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/karmaka.de\/index.php?rest_route=\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/karmaka.de\/index.php?rest_route=\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/karmaka.de\/index.php?rest_route=%2Fwp%2Fv2%2Fcomments&post=13923"}],"version-history":[{"count":3,"href":"https:\/\/karmaka.de\/index.php?rest_route=\/wp\/v2\/posts\/13923\/revisions"}],"predecessor-version":[{"id":14325,"href":"https:\/\/karmaka.de\/index.php?rest_route=\/wp\/v2\/posts\/13923\/revisions\/14325"}],"wp:attachment":[{"href":"https:\/\/karmaka.de\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=13923"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/karmaka.de\/index.php?rest_route=%2Fwp%2Fv2%2Fcategories&post=13923"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/karmaka.de\/index.php?rest_route=%2Fwp%2Fv2%2Ftags&post=13923"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
