CONTINUUM IMAGING FAILED

Continuum

Noise levels:

cont_virgo005 cont_virgo015 cont_virgo016 cont_virgo032 cont_virgo033

paoloserra commented 8 months ago

Line

Note that the measured noise is expected to be higher than the expected natural noise by an amount which depends on the weights used when imaging. For robust = 0 the noise increase is by a factor ~ 1.5.
