We find that the FUV-MAMA has improved resolving power (at the cost of sensitivity) when the repeller-wire high-voltage is turned off. ... To fully realize the increase in resolution provided by this mode, users will have to reprocess the data on their own using the CALSTIS package in STSDAS with parameters set for HiRes pixels. ...

Next: Detection Efficiency Up: CCD Scientific Performance Previous: CCD Scientific Performance . The X-ray energy required to liberate a charge pair in a semiconductor is approximately an order of magnitude lower than in gas detectors, hence the potential spectroscopic advantage of CCD detectors. ... For a number of years, good scientific CCDs attained noise performance of electrons rms, but this limited the energy resolution for X-ray energies 3keV. ...

Limiting Resolution . The terms MTF cutoff frequency, limiting resolution, and resolving power have all been used interchangeably to define the smallest target that can be resolved with an imaging system. Although the term 'limiting resolution' is often used to describe the smallest target length that can be imaged. ... For example, high frequency targets can be reproduced from their low frequency fundamentals and phase errors can produce 'phantom' images that resemble high frequencies. ...
