  • Ticket #110 – Description

    initial v1  
    11Azspec-processed level 1b hawk data does not appear to be correct - it contains large anomalous spikes in some bands, seemingly correlated to very low data values. Eg from Nigg Bay line 3:
    22
     3[[Image(hawk_lev1_spec_az.png)]]
    34
    45Compared to Caligeo spectrum from same pixel:
    56
     7[[Image(hawk_lev1_spec_cali.png)]]
    68
    79Could be underflowing, but would expect a much higher value for the spikes (~65k) in this case. Might still be underflowing and then changed by maths in azspec though.

     11Note extended from ticket #106, but separate to Hawk noise issue
