6 | 1 | Douglas Tucker | z_std = -2.5log10(counts[ADU]/sec) - a_z - k_z*X - b_z*( (i-z)_std - 0.09) ) |

8 | 1 | Douglas Tucker | where: |

9 | 1 | Douglas Tucker | z_std is the standard, or calibrated, magnitude of the star |

10 | 1 | Douglas Tucker | (i-z)_std is the standard, or calibrated, i-z color of the star |

11 | 1 | Douglas Tucker | a_z is the photometric zeropoint in z |

12 | 1 | Douglas Tucker | k_z is the first-order extinction in z |

13 | 1 | Douglas Tucker | b_z is the instrumental color term coefficient in z |

14 | 1 | Douglas Tucker | X is the airmass |

15 | 1 | Douglas Tucker | 0.09 is a "fiducial" reference color for stars in i-z (based on SDSS experience) |

16 | 1 | Douglas Tucker | |

17 | 1 | Douglas Tucker | Note that there is a separate photometric zeropoint (a_i) and |

18 | 1 | Douglas Tucker | instrumental color term coefficient (b_i) for each CCD. |
