... Despite the wide spread use of the terms MTF, CTF, limiting resolution, minimum resolvable target, and contrast to describe CCD image system quality, the terms are often misused and their relations are little understood. ... The modulation transfer function (MTF) is a Fourier transform of the line spread function i.e. its equivalent as an integral sum of sine waves taken over the whole range of spatial frequencies. MTF by its Fourier nature can only be used to operate on sinusoidal frequencies. ...

... While this has been true for me in the last few months, that is not the only reason why it has been such a long time since the last occasion that a SN was discovered with my backyard 41cm telescope. In 1994 there were several amateur discoveries of Sne, either visually or using a CCD as a detector. ... When I awoke there was only fifty minutes left before first light and it took the minutes to get dressed and get the telescope out of the shed onto the observing pad in the back lawn. ...

I would like to propose two new features for the axes annotation in the GMT. 1st: In astrophysics, we often work with great ranges of values (many orders of magnitude). ... However, GMT 3.2 allows to plot annotations for log10 axes every integer log10 value or even more frequently. The proposed patch allows to specify large steps for the log10 axes, in the form illustrated by an example below. 2nd: 10^0 instead of 1, and 10^1 instead of simply 10 do not look beautiful. ... The patch is here. ...

... We have observed and studied critical supercurrents, Ic, in cross-type Nb-Cu/Ni-Nb junctions with Josephson layers prepared from diluted ferromagnetic alloys. For suitable values of the exchange energy in the ferromagnet and the F-layer thickness we have observed Ic(T) oscillation with vanishing Ic for the definite values of T and dF. ... Critical supercurrents, Ic, in Nb-Cu(1-x)Ni(x)-Nb Josephson SFS junctions with F-layers prepared from ferromagnetic Cu(1-x)Ni(x) alloys have been studied. ...

Equinox: The Sun from Solstice to Solstice . ... Today is an equinox, a date when day and night are equal.

... He made observations of a supernova (literally: nova= "new star") in 1572 (we now know that a supernova is an exploding star, not a new star). ... Brahe's meticulous observations showed that the supernova did not change positions with respect to the other stars (no parallax). ... This was early evidence against the immutable nature of the heavens, although Brahe did not interpret the absence of parallax for stars correctly, as we discuss below. Brahe made careful observations of a comet in 1577. ...
