7. White Dwarf WD 1145+017
Photometric Monitoring Observations by Amateur Observer
B. L. Gary, this is the 7th of 7 web pages devoted to my
observations of this object. Last updated 2020.11.20 00 UT
Data exchange files are
available in two formats: light curve details (one line per
image) and dip fits (asymmetric hypersecant (AHS) model fits
for each dip). The first of these is available for download
using the above links (though I recommend that anyone using
these data check with me for updates since I sometimes find
errors and post the corrected files here). Data exchange
files of the second format (AHS dip fits) may be requested
from B.Gary. These may also be available here in due time.
Please don't ask me to co-author a paper! At my age of
almost 80 I'm entitled to have fun and avoid work. Observing and
figuring things out is fun; writing papers is work.
My observations are now "in the public domain" for this
observing season (2018/19). If my data is essential to any
publication just mention this in the Acknowledgement section.
