The results of the computation is printed as table to the command line after each run of ESBO-ETC.
|
|
An exemplary output is shown below for the calculation of the SNR::
|
|
|

└──────┴───────────────┴────────────┘

|
|
Depending on the computed quantity (SNR, exposure time, sensitivity), the layout may vary.
|
|
|
|
Besides the general output of the computation result, some more information is written to files in the output directory (see also :ref:`output_dir`).
|
|
The structure depends on the used detector type.

Imager Detector
|
|
===============
|
|
The signal, background, read noise and dark current in number of collected electrons are written as matrices to separate files.
|
|
These files can be either CSV-files or fits files depending on the settings in the configuration file.
|
|
The data written to these files is reduced to the relevant region containing the photometric aperture.
|
|
Nevertheless, the reduction strategy is written to the file header to allow a lossless restoration of the original pixel matrix.
|
|
An exemplary CSV file may look like this::
|
|
|
|
# Signal in electrons
|
|
# Range reduced to nonzero values.
|
|
# The origin is in the top left corner, starting with 0.
|
|
# Column index range: 507 - 516
|
|
# Row index range: 507 - 516

Heterodyne Instrument
|
|
=====================
|
|
|
|
In case of the heterodyne instrument, the spectral signal temperature, background temperature, RMS noise temperature and SNR are written to a CSV file in the output directory.
|
|
An exemplary output file is shown below.
|
