* The cursor (arrow) keys move the template in redshift and normalisation<br>
* 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). <br>
* Left-clicking the button displayes the coordinates of the pointer position at the time of the click. <br>

Speccy expects plain ASCII text files as input.<br>
Header entries are prefixed by a hash and contain "key = value" pairs. e.g. '# PLATE = 1234'<br>
The main body of the speccy file should contain five comma-separated columns
(with all fluxes in units 10<sup>-17</sup> erg cm<sup>-2</sup> s<sup>-1</sup> &Aring;<sup>-1</sup>):
</p>
<blockquote><samp>Observed Vacuum Wavelength (&Aring;), Flux, FluxError, SkyFlux, ModelFlux</samp></blockquote>
<p>
Template files should contain just two comma-separated columns:
Template files must contain two comma-separated columns:

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