Bandwidth effects on interstellar reddening and on theR-ratio
Astrophysics and Space Science, 1985The energy distributions of 85 stars were combined with the transmittance ofB andV tilters and with an interstellar reddening law in order to investigate the effects of the bandwidth on the colour excess and on the ratioR=Av/E(B-V). Since these depend both on the stellar spectral type and on the quantity of absorbing matter, corrective formulae are ...

The interstellar reddening of the globular cluster 47 Tuc.
Publications of the Astronomical Society of the Pacific, 1975We have estimated the interstellar reddening in front of 47 Tue by observations of 26 foreground A- and F-type stars. The result is E(b- y) = 0021. The zero point may be uncertain by as much as .
