Advanced Compile Options

Use the options here to specify additional information about the object data in your text file.

Object Type

Each of the list boxes in the Object Type column contains a list of all of the available object types. In each list box, select the different object types that are contained in the multiple-type Sky Database that is to be compiled. This information required only when you want to have more than one object type in a single database.

Listed As

Enter the Object Type Identifier from in the source text file that indicates an object of the type listed under the Object Type column. For example, if "GAL" is the Object Type Identifier in the source text file that indicates an object is a galaxy then specify the Object Type as Galaxy and enter "GAL" in the adjacent text box. During compilation of the Sky Database, each line is searched for the corresponding Object Type Identifier character string. If found, the object will be of the type listed to the left.

Multipliers

If any of the required fields present in the text file is not in the in the correct units, the multipliers can be used to adjust them to units used by TheSky.

RA

Type in the multiplier that should be applied to the right ascension during compile. For example, if the RA is listed in degrees in the text file, it must be converted to hours so enter 0.06666667 as a multiplier.

Dec

Type in the multiplier that should be applied to the declination during compile. For example, if the declination is listed in radians in the text file, it must be converted to degrees so enter 57.295778 as a multiplier.

Mag.

Type in the multiplier that should be applied to the magnitude during compile. For example, if the magnitude is listed as a whole number that is ten times the actual magnitude, it must be converted by entering a 0.10 as a multiplication factor.

Major Axis

Type in the multiplier that should be applied to the major during compile. For example, if the major axis is listed in arcseconds it must be converted to arc-minutes by entering a multiplication factor of 0.016666667.

Minor Axis

Type in the multiplier that should be applied to the minor during compile. For example, if the minor axis is listed in arcseconds it must be converted to arc-minutes by entering a multiplication factor of 0.016666667.

Position Angle

Type in the multiplier that should be applied to the position angle during compile. For example, if the position angle is listed in arc-minutes it must be converted to degrees by entering a multiplication factor of 0.016666667.
