ETC

Currently, the ETC-42 accepts the total transmission only as a dataset. There is the need though to use the ETC in a "fast" way, defining for example a constant transmission.

For this reason a plugin should be created which will allow for the generation of some standard transmission datasets. The user should be able to select a range of wavelengths for which the dataset will be created and one of the following types of shapes:

• Continuous: The transmission has the same value (given by the user) for all the range.
• Band-pass: The user gives a range inside which the transmission has a given value and outside it is zero.
• Gaussian: The transmission is a normalized Gaussian. The user should give the central wavelength and the FWHM to describe the Gaussian and the maximum value for which the Gaussian will be normalized.
