The size of font used by PGPLOT for labels and other text on the plots can be changed using the PGSCH command, which takes one argument which is the relative height of the characters. If this argument is greater than one then to font size will be larger than default. ... The easy way to fix this is to call the PGVSTD command after the call to PGSCH. This command allows a sufficient margin for usual labelling, taking into account the current size of the font. ...

The Reflectance of polarized radiation at the incidence angle 12 deg was measured in the range from 1400 to 200 cm -1 for monocrystalline hematite (alpha-Fe 2 O 3 ) and amorphous Fe 2 O 3 samples. Special technique applied allowed to reduce the relative errors downto 1% for the reflectance values of 0.005-0.8. The optical constants were obtained by the Kramers-Kronig method. ...

The black hole. ... The black holes are generated in the result of a collapse of giant stars with the mass more than three Sun's masses. ... And moreover the gas near the neutron star or the black hole will get hot and will become a source of high energetic electromagnetic radiation in X-rays and gamma range. ... In the majority of double systems, being the sources of X-rays radiation, the invisible component mass does not exceed the two solar masses, so it is a neutron star. ...

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. ...
