COMMENTS:


Warning! Speccy is still in development, so please be wary of (and report) unexpected behaviour.

Usage:

http://www.mpe.mpg.de/~tdwelly/speccy/speccy.html?specfile={URL} (substitute URL of a valid speccy file)
* The cursor (arrow) keys move the template in redshift and normalisation
* To zoom into a region: click and hold the right mouse button at one corner of the region of interest, then drag the pointer to the opposite corner of the region where you then release the right button (visual feedback is not yet available).
* Left-clicking the button displayes the coordinates of the pointer position at the time of the click.
* Please send comments, complaints and suggestions to dwelly@mpe.mpg.de.

Speccy File format:

These are plain ASCII text files.
Header entries are prefixed by a hash and contain "key = value" pairs.
Main body should contain five comma-separated columns (with all fluxes in units 10-17 erg cm-2 s-1 Å-1):

Observed Vacuum Wavelength (Å), Flux, FluxError, SkyFlux, ModelFlux

Template files should contain just two comma-separated columns:

Rest-frame Vacuum Wavelength (Å), ModelFlux (Fλ)

Here is a script that can be used to convert a plateful of eBOSS spectra from "spPlate*"+"spZbest*"+"spZall*" format into speccy format:
convert_sdss_plate_to_speccy.csh
