Context The [DASCH archive](http://dasch.rc.fas.harvard.edu/project.php) provides century-scale stellar photometry data. Controversially, KIC 8462852 (an enigma star) had been found to have a significant long-term dimming trend based on DASCH observations (Schaefer 2016). Nonetheless, subsequent studies (e.g. Lund et al. 2016) showed that nominally significant DASCH magnitude slopes are more common that would be expected by chance if the null hypothesis is that stars have a magnitude trend of zero. DASCH slopes from Lund et al. (2016) are made available in this dataset.

Columns are: * Target ID (a Kepler ID or Tycho2 ID) * Full light curve slope (mag/century) * Error * Pre-1970 (Menzel Gap) light curve slope (mag/century) * Error * Post-1970 light curve slope (mag/century) * Error Acknowledgements Dataset files were generously provided by Dr. Michael Lund via email on 10/21/2018.
