This is the Excel spreadsheet for use with the What's the Season? workflow (see list of attributions). It contains the object name, RA, Dec, magnitude, and distance. The spreadsheet was built using the following sources. Dolan (n.d.), Frommert & Kronberg (2007), and Kronberg (1998) were consulted the most, with some RA/Dec values coming from Wikipedia.     Alpha Crucis. (2011, July 28).

Pack What's the Season?


Created: 2011-10-05 05:59:24 | Last updated: 2011-10-05 06:05:50

This pack contains the Excel file for What's the Season?, the workflow itself, and the inputs/outputs used for testing. The inputs/outputs are included in a .zip file. What's the Season? will take a list of astronomical objects and check them against an Excel file. The Excel file currently contains Messier objects with magnitudes less than 6.0 (common names unless the common name is ambiguous or nonexistent, and then it goes by Messier number). It also contains really bright stars. If none o...

The scientific experiment represented by this research object pertains to the multi-wavelength study for a sample of the most isolated galaxies in the local universe. This study characterizes each galaxy of this sample through both the measurement of basic astrophysical properties: - The equatorial coordinates in J2000 epoch - The velocities in km/s (v) - The dust extinction coefficient (ag) - The axis ratio of the isophote 25 mag/arcsec2 (logr25) - The apparent total B magnitude (BT) ...

In order to understand the evolution of galaxies, detailed analysis of images plays a key role. During the last years telescopes working at different wavelengths have been imaging the whole sky. One example of this is the Sloan Digital Sky Survey. The generated images provides a wealth of information, publicly available, and hence allowing them to be used by any interested group in the study of their own samples of objects or generation of new samples.

Workflows (60)

Workflow What's the Season? (1)

Thumb
When given a list of astronomical object names, this workflow will check them against a simple Excel spreadsheet and return which season the object is best observed in. It will also compare the distances to the objects in a Google Charts bar chart. A later version of this may switch to a scatter plot, depending on whether or not this works with the Google Chart API. Running this workflow requires Python. Sys and string should be bundled in Python, but the numpy module will need to be downloa...

Thumb
This workflow takes as input a file for each of this properties: J2000 Coordinates, velocity, galactic extinction, log of axis ratio, and the Total B-magnitude. With this properties it calculates the distance of the galaxy and, in other hand, the total apparent corrected B-magnitude. It takes account if the velocity of the galaxy is lower than a threshold (1000km/s), it can not be possible to calculate the distance so, in those cases the distance will be "NaN". At the end, it calculates the ...

Thumb
It detects if ellipse has failed by checking if the resulting data file exists. It adds a column (validellipse) that contains 1 if ellipse didn't fail and 0 if ellipse failed. It returns a votable that contains all the data with the new column and a votable that contains only the rows where ellipse didn't failed. It uses astrotaverna plugin (http://wf4ever.github.com/astrotaverna/).

Workflow Intialize Sample (2)

Thumb
This workflow saves a tabular *.pckl Python pickle dataset in the local file system, containing values calculated on physical parameters associated to potential companions of a sample of target galaxies. These original physical parameters are extracted from a postgreSQL database, containing information of all galaxies covered by the SDSS spectroscopic survey. The workflow first access the external database located in the AMIGA server and selects the target galaxies from the sample (those havi...

Workflow Discovery of Brown Dwarfs mining the 2MASS... (1)

Thumb
Brown dwarfs are objects occupying the gap between the least massive stars and the most massive planets. They are intrinsically faint objects so their detection is not straighforward and, in fact, was almost impossible until the advent of global surveys at deep optical and near-infrared bands like SDSS, 2MASS or DENIS among others. Here we propose to mine the SDSS and 2MASS databases to identify T-type brown dwarfs through an appropriate combination of colours in the optical and the infra-red...
