For historical reasons, it is useful to offer comparisons between the current WFPC2, and its predecessor WF/PC-1, which was returned to Earth in December 1993. Field format: WF/PC-1 contained 8 cameras and CCDs, each CCD having 800 x 800 pixels. ... Many differences derive from the fact that the WF/PC-1 CCDs were thinned, backside illuminated devices whereas the WFPC2 CCDs are thick, frontside illuminated devices. ... WFPC2 devices have much less CTE error, and hence no preflash is used. ...

... 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 . ...
