Make light curve (dialog)
=========================

The "Make light curve" dialog is used to set up the initial parameters
for a new light curve. 


Activating the dialog
---------------------

The dialog can be activated:

.. |lightcurve_icon| image:: ../../share/icons/lightcurve.png

- from the main menu: :menuselection:`Make --> Light curve`.

- from the main toolbar: |lightcurve_icon|

   Making a light curve


\(1) It is possible to include all source files in the project or the files that are
currently selected in the table of input files. 

\(2) Check this option if you want to include the heliocentric Julian date and heliocentric
correction of the observed object to the resulting data. If so, you have to fill in the 
object's coordinates below.

\(3) Check this option if you want to include the air mass coefficient and apparent altitude
of observed object to the resulting data. If so, you have to fill in the object's celestial 
coordinates and observer's geographic coordinates below.

\(4) By default the light curve consists of differential magnitudes (differences between two
objects). If this option is checked, the light curve will consists of raw instrumental magnitudes,
as they were determined in the aperture photometry. Please note, that the instrumental magnitudes
does not correspond to absolute magnitude of objects and without further processing, these values
are meaningless. 

\(5) Specify object's designation and object coordinates into the edit fields. Enter object's right 
ascension in hours. Use the hexagesimal format, separate the fields by a space character. Enter 
object's declination in degrees. Use the hexagesimal format, separate the fields by a space character.
Click the button (6) to retrieve object's coordinates from a table of predefined objects or a catalog 
of variable stars.

\(7) Specify observer's geographic coordinates into the edit fields. Enter observing location designation
(i.e. city name). Enter the longitude in degrees. Use the hexagesimal format, separate the fields by a 
space character. Enter 'E' character at the first position in a string to indicate that the location 
is on the eastern hemisphere or 'W' character for locations on a western hemisphere. Enter observer's 
latitude in degrees. Use the hexagesimal format, separate the fields by a space character. Enter 'N' 
character at the first position in s string to indicate that the location is on the north hemisphere 
or 'S' character for locations on a southern hemisphere. Click the button (8) to retrieve observer's 
coordinates from a table of predefined locations.

Click the button (9) to proceed.
