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!
