How often are electron-multiplying CCDs used in telescope focal planes? Will Nancy Grace Roman be the first use in a space telescope?
Section I. of The Wide Field Infrared Survey Telescope: 100 Hubbles for the 2020s says: Table 1 summarizes the WFIRST instrument suite, and Figure 1 presents the effective area of the Wide Field ...
Why wasn't CHEOPS data taken during passage through the South Atlantic Anomaly downlinked in this case, resulting in gaps in photometry?
Section 4.1.2. CHEOPS in Six transiting planets and a chain of Laplace resonances in TOI-178 says Due to the low-Earth orbit of CHEOPS, the spacecraft-target line of sight was interrupted by Earth ...
What was the first use of time-delay integration in Astronomy? Are there instances before GAIA?
In the context of GAIA, time-delay integration is the clocking of a CCD's charge shift register at a frequency such that it matches the linear speed across the focal plane of the actual image. So even ...
