... 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 (-...
