The .csv files contain EUVM and NGIMS data that have been interpolated onto a uniform altitude grid and time scale. For every orbit, the data are interpolated onto a uniform altitude scale. The time at for the average of these points is used to interpolate the EUVM data. the density is recorded in the 'density' variable and the EUVM data are recorded for four spectral bands: (0-7 nm = da, 17-22 nm = db, 0-45 nm = dc, 117-125 nm = dd). Auxiliary parameters of local solar time (LST), longitude (lon), latitude (lat), solar zenith angle (SZA), and the distance between maven and the sun (Rs), are also provided. The .p file contains the same data, but with additional fields for the relative changes in both the EUVM and NGIMS data as well as the slope and r value for a linear fit inside of a rolling 27 day bin. The relative change is defined as the 5 day running mean of the 27-day residuals. Additionally, days with high flares are removed as these data may be affected. The .p file is a pickle file, made with python.
