Function to scale failures tackled by countermeasures in burn-in studies of differently sized reference products down to the greatest common chip size of the products and to merge the downscaled information.

`k` |
vector of total numbers of failures for each reference product. |

`n` |
vector of numbers of inspected devices for each reference product. |

`A.ref` |
vector of chip sizes for each reference product (in mm^2). |

`K` |
matrix with entries K[j,i] denoting the number of failures of the j-th reference product tackled with the i-th countermeasure. If two or more countermeasures
have the same efficiency, they can be handled as one countermeasure for several failures. If the i-th countermeasure does not apply to the j-th reference product, then set K[j,i]=0. If there is no countermeasure for a failure at all, then it does not need to be considered in |

`theta` |
vector of (different) effectivenesses of countermeasures. |

`prec` |
precision for greatest common divisor is 10^- |

`tailcut` |
probabilities for scaled failures smaller than |

`phi.cm` |
data frame with possible number of failures |

`A.gcd` |
greatest common divisor of the sizes of the reference products. |
