HK_Project_v2001_NSO

In addition to the 1995 archive, data for 35 stars (essentially, the stars from Lockwood et al. 2007, plus a few additional stars) are included in this release. These observations typically extend through late 2001, i.e., they lack only the final year’s observations. Besides extending the time series for these stars by 6 years, these data may be useful for a more detailed study of calibration variations on that time scale. To distinguish the present data from any other versions that may be circulating among the community, we request that the 2001 files be designated as “HK_Project_v2001_NSO.”
