Dereddening of WISE+2MASS data

  1. May 30, 2013 #1
    Hello friends,

    I was trying to plot the color-color diagram of a particular open cluster using WISE+2MASS data. You can get more details of the diagram from the following paper that i am attaching.[Koenig et.al - Wide Field Infrared Survey Explorer Observations of the evolution of the massive star forming regions-Appendix section -page 22- under the tittle Using 2mass data]. There it is written that we need to do the dereddening for plotting the CCD. And it is written like they have used the extinction law mentioned in Flaherty et al(2009) paper . But i can't understand the law that they have mentioned. Can somebody please help me with a simple explanation?? Pleaseeeeeeeeee...iam stucked up with my work
