Task #63705: Pipeline
Make DB work for Nrec !=2 and UWB work
Added by Huchet Alexandre about 1 month ago.
Updated about 1 month ago.
Description
DB works only for Nrec = 2
UWB doesn't work
The issue is with shapes, at least in the matrix multiplication A = H_out.T * invN * H_out
The DB pipeline is handled differently for Nrec = 2 and other Nrec in JointAcquisitionFrequencyMapMaking.get_operator()
- putting the same code for both cases doesn't make Nrec = 4 work
- actually, DB works for not joint acquisition even if it's the same code for all Nrec
There is code duplication between DB and UWB, namely in QubicDualBand.get_operator() and QubicUltraWideBand.get_operator()
Nrec = 2 corresponds to one reconstructed band at 150 and one at 220 GHz
- since invN is computed in those two bands, might be the issue?
Remarks on the way:
- the noise matrix is not computed with Qnoise
- code duplication between DB and UWB should be removed
- in each method definition, nrec is set to 1 as default, should be changed
- Parent task set to #63705
- Description updated (diff)
