... What work is currently being done to improve the flux calibration accuracy for echelle modes? ... Starting early in Cycle 11, monthly offsetting for echelle modes was turned off to minimize these types of calibration problems. ... We are currently working on redetermining the echelle flux calibration so that it is self-consistent with the 2-D scattered light algorithm. Time dependence of the sensitivity - Sensitivity-monitor data for the echelle modes are currently under investigation. ...

... The choice of which type of electricity is called "positive" and which "negative" was made around 1750 by Ben Franklin, early American scientist and man of many talents (the stamp on the left commemorates his role as first US postmaster--and colonial postmaster before that). ... Franklin knew of two types of electric charge, depending on the material one rubbed. ... Later, when electric batteries were discovered, scientists naturally assigned the direction of the flow of current to be from (+) to (-...

Next: Modes of Operation Up: CCD Scientific Performance Previous: Field of View . Thermal excitation of charge carriers from the valence to the conduction band creates a dark current signal which may vary with position in the array, and also has temporal shot noise variation. ... In a device devoid of localized defects which give rise to individual dark current spikes , most dark current arises from electrons generated at interface states at the surface. ...

The C component of Comet Schwassmann-Wachmann 3 . imaged by Apostolos Christou of Armagh Observatory on 4th April, 2006. ... About one month after its discovery the comet reached its closest point to the Earth (5.73 million miles). ... Current calculations indicate that the main component of the comet, designated SW3C, may reach maximum brightness around May 15th when its distance from the Sun and Earth will be about 93 million miles and 7.5 million miles, respectively. ...

... The star formation rate (SFR) of the current SF episode can be estimated from the total H luminosity. ... For the derived total flux F (H )=5.8 erg s -1 cm -2 we obtain a total H luminosity of 10 39 erg s -1 . ... The total mass of ionized gas can be obtained from the average mass density inside the H II region and its volume. An average mass density corresponding to the average electron density of 1 cm -3 within a volume with a diameter of 0.5 kpc yields a total ionized gas mass of 10 6 . ...

. The following is a list of the currently installed versions of the CIMA. The links refer to the CIMA version log page .

Using a combination of instruments on ESO's Very Large Telescope, astronomers have discovered the most massive stars to date, some weighing at birth more than 300 times the mass of the Sun, or twice as much as the currently accepted limit of 150 solar masses. The most extreme of these stars was found in the cluster R136 in the Tarantula Nebula. Named R136a1, it is found to have a current mass of 265 times that of the Sun. ...
