Now at 500 codes!

Sometimes the codes are easy to find, sometimes they are not. August was a good month. The last of the old codes have been moved over from the old site, associate editor Kim and I had a surprisingly easy time finding codes, and we even had a couple or three codes submitted by their authors. This boosted the ASCL to 500 codes.

Got codes? We want ’em; please share! Submit right on the ASCL itself. Know of a code we don’t have? Please suggest it for inclusion. Just post a reply with any information you have on it. Thanks!

Web Tools and Resources

The ASCL has a thread of web tools and resources for astronomers that we’ve come across while code-gathering. Sometimes these are web versions of downloadable codes in the ASCL; if a code is available only in a non-downloadable version, essentially acting as a black box, it is listed here, too, rather than given a regular entry.

In June and July, we’ve added four new web tools to the thread:

PaperScope, a tool for graphically exploring the Astrophysics Data System (ADS). It’s useful for identifying the citation/reference relationships between papers, and enables the user to visualize these relationships to make locating papers of interest easier.

SpectroWeb, an online maintained interactive graphical database of digital spectral atlases of spectral standard stars.

StarView, an astronomical database browser and research analysis tool.

Time Utilities, which are online applets that convert a list of UTCs to Barycentric Julian Dates in Barycentric Dynamical Time (BJD_TDB), Barycentric Julian Dates in Barycentric Dynamical Time (BJD_TDB) to Julian Dates in UTC, and Heliocentric Julian Dates to Barycentric Julian Dates.

Have a good resource that should be listed? Please add it to the thread; thanks!

A new resource for the ASCL

It’s taken a while to pull it all together, but the ASCL now has an additional portal to the codes in and information about the resource; welcome to the ASCL blog-and-associated-pages site! Some of the information here is also on the ASCL forum. This additional site gives the ASCL more flexibility, however, and includes a quick codes summary page, questions and answers, and a familiar and easy way for people — you? — to submit codes for possible inclusion and make suggestions for and comments on what you’d like to see from the ASCL.
