Abstract : Variations in intensity measurements at 510.0 nm resulting from temperature changes have been recorded using a 0.5-meter Ebert scanning spectrometer equipped with a dual unilateral curved jaw slit assembly. Photons were detected by either a S-13 photomultiplier or a S-5 photomultiplier. The variations were found to be consistent with an effective change of -0.10 plus or minus 0.02 micrometer per degree C in the width of the spectrometer slits and with sensitivity changes of -0.8 and -0.45 percent per degree C for the S-13 and S-5 tubes, respectively.
