EXOPLANET QUERY SELECT PAGE

DATABASE LAST UPDATED ON Saturday 8th of April 2017

SELECT THE DESIRED SPECTRAL TYPE OF EXOPLANET STARS YOU WISH TO QUERY (THE SUN IS TYPE 'G')
NOTE: OFTEN THE SPECTRAL TYPE OF THE EXOPLANET STAR IS UNKNOWN AND AS A RESULT THESE RECORDS WILL NOT BE LISTED




SELECT THE DESIRED FIELD BY WHICH YOU WISH TO ORDER THE QUERY BY.
NOTE: OFTEN THESE PARAMETERS ARE UNKNOWN AND AS A RESULT THESE RECORDS WILL NOT BE LISTED





OPTIONAL ENTRY OF SEARCH STRING.
THIS WILL ONLY RETURN EXOPLANETS/PARENT STARS WITH NAMES CONTAINING THE ENTERED SEARCH STRING.






OPTIONAL ENTRY OF RANKING OFFSET.
THIS WILL ONLY RETURN EXOPLANETS/PARENT STARS WITH A RANKING FROM THAT RANKING OFFSET ONWARDS.
ENTERING A RANKING OFFSET OF "1" WILL RETURN ALL ROWS IN THE QUERY AND IF A NON-INTEGER SUCH
AS "K" OR "89.78" IS ENTERED, THEN AGAIN, ALL THE ROWS IN THE QUERY WILL BE DISPLAYED.
THIS WILL ALSO BE THE CASE IF IT IS LEFT EMPTY OR A VALUE OF ZERO "0" IS ENTERED.
IF A NEGATIVE INTEGER SUCH AS "-78" IS ENTERED, THEN IT WILL BE CONVERTED TO ITS ABSOLUTE VALUE OF "78".






OPTIONAL ENTRY OF PARAMETERS TO ONLY RETURN EXOPLANETS WITHIN DEFINED LIMITS OF BOLOMETRIC HABITABILITY FACTOR
AND (EXOPLANET MASS AND/OR EXOPLANET RADIUS). USEFUL FOR FINDING EXOPLANETS OF EARTH LIKE MASS OR RADIUS IN THE HABITABLE ZONE.

AT LEAST FOUR PARAMETERS NEED TO BE SPECIFIED. NAMELY BOTH LIMITS FOR bolometric_habitability_factor AND BOTH LIMITS AT LEAST FOR radius_earth OR mass_earth.
FOR THIS OPTION TO TAKE EFFECT, THE QUERY MUST BE ORDERED BY AN EXOPLANET PARAMETER.


NO PAIR OF LIMITS CAN HAVE EQUAL VALUES. EG, UPPER AND LOWER BOLOMETRIC HABITABILITY FACTOR LIMITS CANNOT BOTH BE EQUAL TO 1.5.
IF ANY PARAMETER IS INADVERTENTLY ENTERED AS A NEGATIVE NUMBER, IT WILL BE CONVERTED TO ITS (POSITIVE) ABSOLUTE VALUE. EG, -1.3 BECOMES 1.3.
IF AN UPPER LIMIT IS INADVERTENTLY ENTERED WITH A LESSER VALUE THAN ITS CORRESPONDING LOWER LIMIT, THEN THE VALUES WILL BE SWITCHED.
ANY NON-NUMERICAL ENTRY OR EMPTY FIELD WILL DEFAULT TO ZERO, AND IF TWO OR MORE PAIRS OF DATA ARE EQUAL, THIS OPTION WILL BE REJECTED COMPLETELY IN THE QUERY.

LOWER BOLOMETRIC HABITABILITY FACTOR LIMIT
UPPER BOLOMETRIC HABITABILITY FACTOR LIMIT
LOWER RADIUS LIMIT FOR EXOPLANET IN EARTH RADII
UPPER RADIUS LIMIT FOR EXOPLANET IN EARTH RADII
LOWER MASS LIMIT FOR EXOPLANET IN EARTH MASSES
UPPER MASS LIMIT FOR EXOPLANET IN EARTH MASSES
