Thoughts on Archives
I am quoting here from "Light Curves of Variable Stars" by Sterken and
Jaschek. I found time to read through this book several times on my
vacation while Jennifer was participating in Rolls events and visiting with
her relatives. Seems like the Malpass family delights in going to some
remote place, and then seeing how many near by (or not so near by) friends
and relatives can come by to visit. I thus found time to read while
keeping out of the way of the melee.
From the Introduction (sic):
"We first intended to present all data (light and colour curves) in one single
photometric system and to represent the data with a single graphical software
package. However, as the light curve data were coming in, we realised that
it was
just impossible to combine all photometric data into one singe homogeneous
data set. Moreover, we learned with dismay that for many light curves
published
less than a decade ago, the only remnant data are the graphs themselves, the
original data having been lost forever - indeed a vivid demonstration that
archiving of astronomical data is still in its infancy.
Here are some of my thoughts on this:
1) A big data base in consistent format would allow Sterken and Jaschek to
do what they wanted to do. Present curves in "one single photometric
system and to represent the data with a single graphical software
package". Note that when S and J set out to do this work (a graphical
catalog of variable star types) they were surprised that no one seemed to
have done it before.
2) Until there is some place else to put the data, i would propose that
people like Michael K. put their data into technical notes *including the
raw data*. The format is not important. No use doing work twice to put
the data into some format of our own. Just write it up for the destination
journal and make a tech note of it. Then append the raw data. Then
someone that wants the information can come and get everything.
Again, this is not publication. It is our "internal" archive. No matter
that anyone can participate in tass and thus access the data.
