In order to check whether the 4-degree objective prism spectra can be used for deep spectroscopic studies of galactic structure, we measured the Rose(1984)'s seven indices between 3500 A and 4400 A for 19 Hyades stars on the Kiso Schmidt prism plate, K3496. By comparing the 4∘ 4∘ -indices with those of Rose(1984), we have found that Hδ/FeI Hδ/FeI , Hγ/4325 Hγ/4325 , and P(3912)/P(CN) measured on the 4-degree prism spectra, are still useful for the derivation physical parameters.
