|HST Primer for Cycle 25|
The WF/PC had two configurations; in both channels, the field of view was covered by a mosaic of four charge-coupled devices (CCDs). Each CCD had 800 × 800 pixels and was sensitive from 1150 Å to 11,000 Å. However, internal contaminants on the camera optics limited normal operation to the range from 2840 Å to 11,000 Å.In the Wide Field Camera (low-resolution) configuration, the field of view was 2.6' x 2.6', with a pixel size of 0.10". In the Planetary Camera (high-resolution) configuration, the field of view was 1.1' x 1.1' and the pixel size was 0.043". A variety of filters were available. The WF/PC received about 40% of the observing time on HST from Cycles 1 to 3, resulting in a large and diverse range of science data. All WF/PC data were severely affected by the spherical aberration. Unique and valuable data exist in the archive, but in terms of photometric accuracy, and especially image quality, imaging data taken after the first servicing mission are superior.
