Hi Simone,
What you are discussing is for sure handled by Qpack2.
For old Qpack I am not sure. Sorry.!
The README file indicates that it is not allowed. On the other hand, the
function handling the task handles it:
%------------------------------------------------------------------------
% NAME: hBackendFromFile
%
% Includes into H a backend where the channel response is defined
% in a file. Channels can (1) have the same response, or (2) have
% individual responses. The channel file shall have ARTS
format. For
% case common repsonse, it shall be a 2 column matrix, where
column 1
% is (relative) frequencies and column 2 is response values. For
% individual resposnse channel, it shall be an array of matrices,
% where matrix {i} shall be a 2 column matrix giving the response
% of channel {i}, also column 1 frequencies and column 2 response
% values The response of the channels is normalised and the
% response values do not need to be normalised.
%
However, it could very well be the case that this option never has been
tested.
So you could test and hope for the best!
Bye,
Patrick
