Command line unix tools for Exploration of Astronomical Objects

These command line bash programs, written by SR Kulkarni, are useful for quick gathering of information of a small samples of astronomical objects. The philosophy behind this suite is similar to Unix: each tool does one thing (hopefully very well) and tools can be chained (ouputs can be piped).

I am continually updating the programs. The latest version of the tools, packaged as a tar file, can be found here. Potential users: please reload on a weekly basis (until the package suite is stable). Feedback is appreciated.

Installation: You need to install the entire suite (there are modest dependencies; for example, mdrGaia calls csGaia etc). Also SRKutils relies on tools that are not a part of the vanilla Unix system:

gdate, gjoin, gsed, jq, textutil, csv package (csvcut, csvlook, csvjson...)

(may be others but need feedback). Next, if the tool you are invoking calls TNS or ADS then you need tokens defined as follows:

export ADS_TOKEN="xxxxxx...."
export TNS_API_KEY="yyyyy...."
