Yes, it is:
'Exoplanet Observing for Amateurs', online book home page
http://brucegary.net/book_EOA/x.htm
online book
http://brucegary.net/book_EOA/EOA.pdf
with the exoplanet LCs at:
Amateur Exoplanet Archive (AXA)
http://brucegary.net/AXA/x.htm
He obviously got your 6 exoplanet LCs from March to June and added
them to the AXA pages.

His home pages at:
Bruce Gary's ASTROPHOTOS (new)
http://reductionism.net.seanic.net/brucelgary/AstroPhotos/x.htm
and
Bruce's Amateur Astronomer Research Projects (old)
http://brucegary.net/x.htm
are really worth to spend a rainy weekend with and his photometry
pages and tutorials are especially worth a look:
Photometry for Dummies
http://brucegary.net/dummies/x.htm
Photometry for Smarties
http://brucegary.net/photometry/x.htm
CCD Transformation Equations
http://reductionism.net.seanic.net/CCD_TE/cte.html
All-Sky Photometry and Differential Photometry Iterative Procedure (DPIP)
http://brucegary.net/AllSky/x.htm
... and many more.

Clear skies
