The last measurements made with the Wampler scanner. IV. Semicontinuous scans of G and K stars.

TAYLOR B.J.

Abstract (from CDS):

New semicontinuous scans (with nearly contiguous passbands) are presented for α CMi and for 24 G and K giants. In addition, 12 such scans published in 1984 are reduced to an up-to-date standard-star system and adopted. The collected scans range from 3288 Å to at least 6940 Å, and they have been standardized to a system defined by α Lyr. They are supplemented by measurements of 23 of the program giants using six near-infrared passbands. Tests of the consistency and accuracy of the data yield encouraging results. The scans are used to test and response curves published by Bessell, and it is found that if those curves are weighted by wavelength (as Bessell proposes), they yield an acceptable wavelength baseline fori B-V. The scans are also compared to a solar irradiance curve published by Lockwood et al. and standardized by measuring α Lyr. At wavelengths greater than 5248 Å, the Lockwood et al. curve appears to be ``too blue'', and a correction equation is proposed. However, that curve yields a satisfactory synthetic value of and good agreement with a comparable stellar scan at wavelengths ranging from 4100 Å to 5207 Å.
