A problem, that can arise when moving from Fortran 77 to Fortran 90, is dependent on a usual deviation from the standard, and has to do especially with user programs. ... With many Fortran 77 implementations we wrote PROGRAM TEST REAL X WRITE(*,10) 10 FORMAT('Give X = ',$) READ(*,*) X WRITE(*,*) X END In Fortran 90 we use "non-advancing I/O" instead. ... In some old Fortran dialects the statement TYPE was used to write on a typewriter terminal and PRINT was used to write on the line printer. ...

In Actor Prolog a resident is a special mechanism that helps processes to inspect state of other processes. A resident observes the state of a specified (target) process and if the state of the process changes (for instance, after message handling) it proves a specified predicate of the process. ... Work of the resident. ... Any change of the list of target processes or arguments of resident function results in activation of the resident and repeated collection of information in the target worlds. ...

Observing with ESO Telescopes . ... The default use of the visir_img_combine recipe of the VISIR pipeline is with the "ref" option set to false. ... The VISIR pipeline will create the combination of the nodded images using the ESO SEQ CUMOFFSETX and ESO SEQ CUMOFFSETY offset information in the fits file headers. ...

... Restrictions ) are used. If specified form of output is EMP then astrometric equatorial coordinates are printed in the form usual for Ephemerides of Minor Planets, with formal precision of 0.01 minute of time in R.A. and 0.1 minute of arc in declination. ... It should be noted that the near-opposition ephemerides are not calculated for bodies/ points with numbers from –12 to 0 (in case they are included into task for computation of such ephemerides only their names are displayed in the results). ...

Most commonly, binoculars utilize either porro prisms or roof prism s for this purpose. ... Example: The Meade 8x42mm Waterproof roof prism binocular has a field of view 367 ft. wide for an object 1000 yards distant from the observer, yielding a field of view specification of 367 ft. at 1000 yds. ...

... For more distant stars we must use other techniques. ... Hence if we see a distant galaxy and can pick out any cepheids lying within it, we can calculate its distance. ... Here then is another method to gauge the size of the Universe and there are yet more. volume at high enough temperature a nuclear fusion reaction sweeps across the white dwarf's surface and eventually we will see a spectacularly bright new star (hence nova) in our skies. ... Why is this relevant to the size of the Universe? ...

Allows you to specify a drift scan: motion at a constant velocity along a great circle. ... The path starts at the new object position (though the telescope actually intersects the path later, see Subtleties ). ... Note that the units are always /sec for both axes. ... The velocity along the path is 0.01 /sec. ... The path is assumed to start when you hit the Slew button (more precisely, when the TCC parses the command). However, it takes the telescope awhile to slew to meet the specified path. ...

... The Galactic low-mass X-ray binary GS 2023+338 was discovered during the burst on May 22, 1989 with the Japanise satellite Ginga (aka Galaxy). The flux reached 17 crabs (this unit of flux measurement is an bright X-ray source, Crab Nebula) at 10-35 keV. ... No other radio telescope worldwide carried out multi-frequency measurements. ... Upon 14 days the radio flux fell below the detection level at the RATAN-600 in relation to the decrease of the X-ray flux. ...
