To be read in conjunction with Section 4.11 of the WFPC2 Instrument Handbook , -Version 4.0. ... 1 The second study found evidence that CTE loss for faint stars has increased with time (Whitmore, 1998). The primary observational consequence of CTE loss is that a point source at the top of the chip appears to be fainter than if observed at the bottom of the chip, due to the loss of electrons as the star is read out down the chip (see Figure 1 ). ...

Use on openSUSE =============== All of the recent development for XmCCD and XmTel has been on openSUSE systems. No recent version of Suse Linux includes Motif or fxload by default, so you will have to install them. ... For fxload, use the rpm from the appropriate openSUSE version (fxload has to be patched differently for each version). ... You could use 10.2 and create the needed kernel components, but for new installations version 10.3 appears to be a better solution. ...
