    initial v1  
    33The custom pinhole smearing is working exactly as the code is written. This option computes dQ for each Q value that is linearly interpolated between the set minimum and maximum, but these dQ values are not based on the Q values. In the data file the faked dQ values were 8% of Q across the entire Q range.

    5 The confusion stems from the difference in behavior between how dQ slit smearing and custom slit smearing work. If the minimum and maximum dQ are the same in the two cases, the results are different, but that is because the intermediate dQ values will likely not be the same.

    7 The question I was asking and still have: should we keep custom slit smearing as it is currently or should we change how the intermediate dQ values are calculated to better represent reality? I offered two ways to do this; (1) a fixed percentage of Q regardless of the Q value, or (2) a variable %Q, interpolating between the %Q values calculated using the input min and max dQ.
