See the original paper for details on the data reduction. Please reference the original paper if using these datasets. 

1) STIS_2mj05215.mrg

The file includes the three-ranges spectra extracted and combined: G230L+G430L+G750L. Ascii file. Columns are: WAVELENGTH (˚A), COUNT-RATE (counts cm−2 s−1 pixel−1), FLUX (ergs cm−2 s−1 ˚A−1), STAT-ERROR (ergs cm−2 s−1 ˚A−1), SYS-ERROR (ergs cm−2 s−1 ˚A−1), NPTS (the number of co-added spectra for that pixel), TIME (total exposure time at that pixel in seconds), QUAL ( 1=good data, 0=possibly poor data quality). The DOI: 10.17909/tvvw-4e47 refers to the original HST data, not to te reduced and combined dataset.

2)  UVITimages.tar.  Tar file containing the UVIT images, reconstructed from the photon-counting archival data, calibrated accounting for dead-time corrections, in .fits format

The tar file contains the following .fits files of the reconstructed images, where the “NORM EXPARRAY” files are the normalized relative response maps across the field, expressed as 0 to 1. So, the effective exposure time at a pixel position is RDCDTIME multiplied by this image. The ”NORMEXP IMAGE” is the science image, that must be divided by the product of RDCDTIME and the NORM EXPARRAY image on a pixel-by-pixel basis, to obtain counts s−1 pixel−1
