ism3d.arts.discretize.lognsigma_lookup(objs, dname)[source]
update some model parameters related to likelihood calculation

In the model properties, we have some keywords related to configing the likelihood

model and calculate log_propeorbaility:

lognsigma: used to scale noise level (in case it’s overunder estimated)

They are actually related to data (one value per dataset) But it’s setup per object due to the input file layout (repeated for different objects, like PSF) # we expected lognsigma is the same for one dname from all objs
