Message-ID: Hi all, It seems everything has been done. However I have tried many times and can not install or initialize it successfully. I follow the installing method here ( http://ssb.stsci.edu/ureka/dev/docs/installation.html) First I download Ureka_linux-rhe5_64_1.4.1.1. tar.gz from http://ssb.stsci.edu/ureka/1.4.1.1/docs/installation.html#ur-test and extract it to /usr/Ureka .

It is possible to have multiple copies of Ureka on your system. To distinguish them, you give each a name. You can use this name later with ur_setup to choose which copy of Ureka you want to use. You have no existing Ureka installs configured The name can only contain letters, digits, underline and dash. Enter an installation name: ureka Ureka needs to add a few lines to your login scripts. It can check if they are already there and automatically add them if needed. Answer yes unless you know a particular reason to answer no. Automatically configure login scripts? Enter yes or no [yes]: y WARNING - y is not a valid response Automatically configure login scripts? Enter yes or no [yes]: yes ====================================================================== Ureka is installed. Log in a new terminal window and type the command ur_setup or ur_setup common ureka to select your Ureka environment. 'ur_setup -h' will show some help. After I run ur_test, if I run ur_setup in the same window, ur_setup can be recognized. No 'ur_setup: command not found...' will appear. If I continue in the same window, for example, I run 'ecl', it will let me configure the variables. How to configure the variables? And if I open a new terminal window, ur_setup will not be recognized. Anybody is running Ureka successfully? Who knows how to solve the problem above?

This is not a how-to question about Python programming, so although it is technically off-topic, it is very much related to the interests and technical talents of the community. Numerous Astropy subscribers are involved in writing astrophysical modeling software; this is an opportunity to review a new model and write new, theoretically cutting-edge software that can be used to confront astrophysical observations with the model. The mathematics is straightforward and can be very easily implemented in Python. I am certain that somebody on this list is going to create something extraordinary based on this new material, which may likely to be associated with a future journal article in ApJ, AJ, etc. I do not have the time to do that any time in the near future and, regardless, I am certain that the talent pool on this list far exceeds my own programming capabilities. See < http://sensibleuniverse.com/slides > for a PDF that describes the model for which no software has yet been written, other than the included SQL code for source SDSS DR10 data. If you are a university student through post-doc and have a great idea, please reply direct with your suggestion (.edu required) and I can probably get you some funding for the project.

Our goal is to write a scalable open source Python/C++ data processing and analysis system for LSST, while reusing code (and contributing to) existing community efforts whenever possible. If you get warm fuzzies at the thought of collaboratively writing a system that will process petabytes of data on 150k+ cores, enable research ranging from killer asteroids to dark energy, and add to the open source codebase that the community can reuse in the future, please give us a look!

SEP makes available some of the algorithms in Source Extractor as stand-alone functions and classes. These operate directly on in-memory arrays (no FITS files, configuration files, etc). The code is derived directly from the Source Extractor code base. Changes from v0.1.0: - new aperture photometry functions - Kron radius function - variable detection threshold in object detection - bug fixes - better documentation: http://sep.readthedocs.org Source code: https://github.com/kbarbary/sep The new version is almost entirely backwards-compatible with v0.1.0, but there are some deprecations. See https://github.com/kbarbary/sep/blob/master/CHANGES.md. Finally, note that SEP overlaps with some of the functionality in photutils, and in fact some code originally written for photutils has been added to SEP. We've discussed including SEP as a "low-level" dependency in photutils and this release is a step towards enabling that.

Sloan Foundation and support research in data intensive science (with astrophysics one of the core components of data science at UW). Up to four Fellowships will be awarded in 2015. Fellows are provided with annual salary support of $65,000 for two years, with a possible extension for a third year, and a research stipend of $25,000 over the total period of the appointment that can be used for travel, equipment, software, undergraduate research assistants, or other research costs. If you, or any postdocs or graduate students you know, are interested in data intensive astrophysics please encourage them to apply.

Incidentally, there is an open issue for exactly this (patches welcome :): https://github.com/astropy/astropy/issues/3058 On 12/17/2014 11:41 PM, J. Xavier Prochaska wrote: > I don?t recall where I pulled this syntax, but it works fine: > > prihdr = fits.Header() > prihdu = fits.PrimaryHDU(header=prihdr) > > #data is an astropy Table > table_hdu = fits.BinTableHDU.from_columns(np.array(data.filled())) > > thdulist = fits.HDUList([prihdu, table_hdu]) > thdulist.writeto(outfil,clobber=True) Xavier's workaround is good for now. However, there are parts of it that are unnecessary. For example, creating an empty primary HDU is unnecessary unless you intend to put additional keyword in the primary header. Otherwise just: table_hdu.writeto(filename) will suffice (no need for any of the intermediate steps). Also I think table_hdu = fits.BinTableHDU.from_columns(np.array(data)) is good enough in most cases. Calling filled() is only necessary if you have masked data. So really, getting a BinTableHDU from a Table boils down to the one line above.

For example, among currently defined systems, can I overplot a grid of galactic coordinates on top of a RA-dec grid? As an aside, is there planned support for Ecliptic coordinates?
