| Since the amplitudes from the toolbox are in units of the Tcal one just have to multiply the given numbers by the Tcal to get the correct system temperature. The reduce.py procedure provides an all.fit file that contains all the single fit-files. The further programs work with this all.fit. | Since the amplitudes from the toolbox are in units of the Tcal one just have to multiply the given numbers by the Tcal to get the correct system temperature.

| - | The script **weather.py** reads the weather information for the MBFITS files, multiplies the Tsys found in the all.fit by a given Tcal and prints out a weather.dat and a LIST.tsys, with the opacity information for each scan that is listed in the scanlist-file. The minimum zenith opacity is fitted from the Tsys vs. airmass distribution and is presented in the plot Opacities.eps.

It multiplies the Tsys found in the all.fit by a given Tcal and prints out a LIST.tsys, with the opacity information for each scan that is listed in the scanlist-file. When the weather data is read from the raw MBFITS file the script will write a new weather.dat for alter use. The minimum zenith opacity is fitted from the Tsys vs. airmass distribution and is presented in the plot Opacities.eps. Weather.eps contains the weather info. |
