.Perl ADS
These perl scripts are used to access the ADS database in an easy way, directly from the shell prompt. They are usefull to build a bibtex database, retrieve pdf files of a list of paper, or to make simple statistics. There is two sets of scripts : the first one, somehow older, is based on LWP::UserAgent to access directly ADS web pages. The second is a rewrite of the latter using the Astro::ADS library.

In order to make batch reduction with CRUSH, I also wrote some shell scripts to simplify this process.
You have to change the config.sh to set the correct path for your configuration. You also need to create a target_sources file in the $LIST_DIR directory which list all your target sources name as reported in the fits files. Run the make_list.sh script to produce scan list for each target source. You can now reduce the complete project by running reduce_target.sh or individual sources with reduce_source.sh source_name

You have to change the default path in read_scan.pro, and then you case use the plot_scan routine with a least one argument, the fits file name, to display the signal (default), the noise (/noise), the signal-to-noise ratio (/s2n), or the integrated time (/time). You can also smooth the map to the FWHM of the CSO (/smooth), force the correct aspect ratio of the image (/aspect), crop the pixel with integrated time less than a value (crop=value), put a cross on the pointed position (/cross), change the display of the axis - offset (default) or absolute (/type), change the contours wrt to time (contours_time=[0,5]), and suppress the wedge (/nowedge)
The plot_scan routine is in fact more geneal and could be use with any kind of astronomical image, as long as the structure returned by the read_scan routine is filled with the right values.

Deriving line parameter from a UVFIT in the Grenoble Image and Line Data Analysis System is not an easy task. I developped a few program to be able to do it easily. First you should patch the gio library of GILDAS in order to be able to save uvfit result in fits format. The task gildas_fits or fits will then be able to save UVFITS result table in fits format (use standard fits format and number of bits=-32). The resulting fits file can then be used to derive line parameters, for example with the IDL script included, using the Markwardt IDL Library to make the fit. The very usefull TexToIDL library is also used to legend the plot. Uncertainties on the fitted line parameters are derived from spectra uncertainties, computed from the visibilities and thus does not required the complex process of deconvolution/reconvolution involved in the mapping of interferometric data.

To easily use and test the Astronomical SURVival Analysis package, I wrote a simple C wrapper which can be directly be called, as a library, from IDL or other language/program. This work has been highly simplified by the splitting of the original monolitical code of ASURV by the Starlink project. The univariate two sample tests, bivariate correlation tests and linear regression have been wrapped.
IDL Statistic
Two very usefull routines to plot the histogram and the partition function of a dataset. The first use the IDL histogram function but also compute the proper abscissa.
