Then, too, we can sometimes overlook the low end:

    http://users.rcn.com/rflrs/Ptz10-02x.atm   ATMOS input file
    http://users.rcn.com/rflrs/Ptz10-02x.len   OSLO input file
    http://users.rcn.com/rflrs/Ptz10-02x.txt   TEXT prescription
    http://users.rcn.com/rflrs/Ptz10-02x.zmx   ZEMAX input file


In OSLO and ATMOS, I entered B270 in direct specification, using
the refractive indices calculated by ZEMAX.
