//  Preliminary description of the calibration in photons (email from 12/02/04)
//
//  Why calibrating in photons:
//  ===========================
//  
//  At the Barcelona meeting in 2002, we decided to calibrate the camera in
//  photons. This for the following reasons:
//  
//  * The physical quantity arriving at the camera are photons. This is
//    the direct physical information from the air shower. The photons
//    have a flux and a spectrum.
//  
//  * The photon fluxes depend mostly on the shower energy (with
//    corrections deriving from the observation conditions), while the photon
//    spectra depend mostly on the observation conditions: zenith angle,
//    quality of the air, also the impact parameter of the shower.
//  
//  * The photomultiplier, in turn, has different response properties
//    (quantum efficiencies) for photons of different colour. (Moreover,
//    different pixels have slightly different quantum efficiencies).
//    The resulting number of photo-electrons is then amplified (linearly)
//    with respect to the photo-electron flux.
//  
//  * In the ideal case, one would like to disentagle the effects
//    of the observation conditions from the primary particle energy (which
//    one likes to measure). To do so, one needs:
//  
//    1) A reliable calibration relating the FADC counts to the photo-electron
//       flux -> This is accomplished with the F-Factor method.
//  
//    2) A reliable calibration of the wavelength-dependent quantum efficiency
//       -> This is accomplished with the combination of the three methods,
//          together with QE-measurements performed by David in order to do
//          the interpolation.
//  
//    3) A reliable calibration of the observation conditions. This means:
//       - Tracing the atmospheric conditions   -> LIDAR
//       - Tracing the observation zenith angle -> Drive System
//
//    4) Some knowlegde about the impact parameter:
//       - This is the only part which cannot be accomplished well with a
//         single telescope. We would thus need to convolute the spectrum
//         over the distribution of impact parameters.
//  
//  
//  How an ideal calibration would look like:
//  =========================================
//  
//  We know from the combined PIN-Diode and Blind-Pixel Method the response of
//  each pixel to well-measured light fluxes in three representative
//  wavelengths (green, blue, UV). We also know the response to these light
//  fluxes in photo-electrons. Thus, we can derive:
//  
//  - conversion factors to photo-electrons
//  - conversion factors to photons in three wavelengths.
//  
//  Together with David's measurements and some MC-simulation, we should be
//  able to derive tables for typical Cherenkov-photon spectra - convoluted
//  with the impact parameters and depending on the athmospheric conditions
//  and the zenith angle (the "outer parameters").
//  
//  From these tables we can create "calibration tables" containing some
//  effective quantum efficiency depending on these outer parameters and which
//  are different for each pixel.
//  
//  In an ideal MCalibrate, one would thus have to convert first the FADC
//  slices to Photo-electrons and then, depending on the outer parameters,
//  look up the effective quantum efficiency and get the mean number of
//  photons which is then used for the further analysis.
//  
//  How the (first) MAGIC calibration should look like:
//  ===================================================
//  
//  For the moment, we have only one reliable calibration method, although
//  with very large systematic errors. This is the F-Factor method. Knowing
//  that the light is uniform over the whole camera (which I would not at all
//  guarantee in the case of the CT1 pulser), one could in principle already
//  perform a relative calibration of the quantum efficiencies in the UV.
//  However, the spread in QE at UV is about 10-15% (according to the plot
//  that Abelardo sent around last time. The spread in photo-electrons is 15%
//  for the inner pixels, but much larger (40%) for the outer ones.
//  
//  I'm not sure if we can already say that we have measured the relative
//  difference in quantum efficiency for the inner pixels and produce a first
//  QE-table for each pixel. To so, I would rather check in other wavelengths
//  (which we can do in about one-two weeks when the optical transmission of
//  the calibration trigger is installed).
//  
//  Thus, for the moment being, I would join Thomas proposal to calibrate in
//  photo-electrons and apply one stupid average quantum efficiency for all
//  pixels. This keeping in mind that we will have much preciser information
//  in about one to two weeks.
//  
//  
//  What MCalibrate should calculate and what should be stored:
//  ===========================================================
//  
//  It is clear that in the end, MCerPhotEvt will store photons.
//  MCalibrationCam stores the conversionfactors to photo-electrons and also
//  some tables of how to apply the conversion to photons, given the outer
//  parameters. This is not yet implemented and not even discussed.
//  
//  To start, I would suggest that we define the "average quantum efficiency"
//  (maybe something like 25+-3%) and apply them equally to all
//  photo-electrons. Later, this average factor can be easily replaced by a
//  pixel-dependent factor and later by a (pixel-dependent) table.
//
