The variability of UV extinction-curve shapes and its impact upon dereddened UV energy distributions
The magnitude-limited survey provided by ANS satellite data is used toinvestigate the global variability of the shapes of UV extinction curvesand the errors these variations introduce into the UV continua ofreddened objects. Results show that although variations in UVextinction-curve shape are largest in regions of dense nebulosity, theerrors incurred by using a mean curve to deredden an energy distributionare still significant. It is suggested that debumping should be avoidedwhenever a reliable E(B-V) is available, and that errors in dereddenedUV colors can be reduced by employing a local mean extinction curve.
