comment How LOFAR pass through the ionosphere?
LOFAR corrects for the ionosphere in its calibration procedure. If you're looking for a technical discussion take a look at LOFAR's calibration methods: here and here

comment Birth and Evolution of Millisecond Pulsars
@HDE226868 - You're absolutely right, gravitational wave emission could lead to an in spiral, but this is only relevant for extremely tight binaries. For the situation considered here the evolution is completely dominated by mass transfer.

comment Could a habitable satellite of a gas giant have a stable subsatellite?
@zibadawatimmy - Actually 0.03 AU is about 2.5 times further out than Callisto and nearly 7 times the orbital radius of Europa. By the very nature of this calculation the tidal effects caused by Jupiter' are -exactly- the same as those the Sun exerts on Earth. You're right about habitability though, although I think the main factor will be the highly variable irradiation received from both the Sun' and Jupiter'.

comment How do you model galactic noise based on raw signal data?
One man's noise is another man's signal (if you'll excuse the gender stereotype), so without knowing what it is you're trying to measure there is no way to answer this. Could you give some more information?

@feralin sorry, I meant to say apparent magnitude

comment Compute Planet's Apparent Visual Magnitude
@feralin As a second note; if you want to model an inferior planet you can simply make the reflective surface - A - depend on (synodic) orbital phase.

comment Compute Planet's Apparent Visual Magnitude
@feralin I guess you can, but you'd still need a second parameter to normalize the conversion, be it either the relative magnitude of the sun or an absolute magnitude of a calibration star. Using the relative magnitude of the sun would make sense here and probably gives a more direct final expression, but I think using luminosity gives a better sense of what's physically going on.
