title: Data Products for "NASA's Pandora SmallSat Mission: Simulated Performance of Stellar Characterization and Contamination Correction"

description: This dataset contains the simulated Pandora VISDA and NIRDA observations used in the paper, "NASA's Pandora SmallSat Mission: Simulated Performance of Stellar Characterization and Contamination Correction."

The data products include native-cadence and 12-hr binned spectrophotometric time series for eight stellar spot scenarios (K and M dwarfs; fast and slow rotators; giant and solar-like spot morphologies). Each file contains count-rate measurements (e⁻ s⁻¹), associated 1σ uncertainties, and corresponding spectral flux densities (erg s⁻¹ cm⁻² Å⁻¹). Units are stored as HDF5 dataset attributes.

The simulated observations incorporate photon noise (Poisson statistics based on total electron counts), background and dark current contributions, and read noise, combined in quadrature. A fixed random seed was used for the noise realization to ensure reproducibility. The 12-hr products are constructed from pre- and post-transit windows for ten visits per scenario, excluding ±1 hour around transit center.

title: ISIS-2 Topside Sounder Average Ionogram over Fairbanks, AK: ULA, Latitude 65, Longitude 212

description: These Ionograms were digitized from the original ISIS-2 7-Track Analog Telemetry Tapes using the Facilities of the former Data Evaluation Laboratory at the NASA/GSFC. This Data Restoration Project is headed by Dr. R.F. Benson (NASA/GSFC). Ionograms were digitized at the Rate of 40,000 16-bit samples/s. This Sample Rate is higher than the Nyquist Frequency of 30 kHz. The Sample Frequency of 40 kHz provides a Measurement every 25 µs corresponding to an Apparent Range Interval equal to 3.75 km from c*t/2, where c is the Speed of Light. Ionograms with this Sample Rate are designated as 'Full' Ionograms because they have the full 3.75 km Apparent-Range Resolution. The Ionograms used for most Analyses, and those available from CDAWeb, were produced by averaging every four Samples of the Sounder-Receiver Video Amplitude Output to yield an average Value every 100 µs corresponding to an Apparent-Range Resolution of 15 km. These Ionogram Files are referred to as 'Average' Files with Standard Resolution. Each Ionogram consists of a Fixed-Frequency Portion and a Swept-Frequency Portion. The Time Resolution between Ionograms is typically 14 or 22 s depending on the Frequency Sweep Range.

title: ISIS 2 CRC Electron Density Profiles

description: This data set, provided by the Communications Research Centre (CRC) in Ottawa, Canada, consists of electron density profiles for the ionosphere above the F2 maximum (topside ionosphere). The data are computed from digital values of frequency and virtual height, scaled from ionograms that are measured by the ISIS 2 (International Satellites for Ionospheric Studies) Swept-Frequency Sounder. The data are ordered chronologically. Telemetry stations are not identified, but satellite location, Greenwich mean time of observation, solar zenith angle at the satellite, dip latitude at the satellite, total electron content down to the lowest height of topside signal reflection (normally near 300 km), and other relevant information is noted with each profile. The format gives sequences of numbers for each point scaled from the ionogram. These sequences include electron density at the successive points, and the coefficients a2, b3, b4, b5, etc. from which geometric heights can be calculated, using formulas 40 and 41 in J. E. Jackson, "The reduction of topside ionograms to electron-density profiles," Proceedings of the IEEE., p. 960, June 1969. These formulas can also be used to calculate interpolated density-height values. A CRC interpolation program (available at NSSDC) can be used with this data set.
