Questions and formulas:
Question: what is the right ascension (j2000) when the apparent magnitude is 13?
Formula: LET(query1,SUMMARIZE(D1,SUMX(F1)),FILTER(query1,CHOOSECOLS(query1,2)=13))
Formula2: LET(query1,SUMMARIZE(D2:D12,SUMX(F2:F12)),FILTER(query1,CHOOSECOLS(query1,2)=13))
Level: hard
Question: what is the constellation when the right ascension (j2000) is 09h51m54.0s?
Formula: UNIQUE(CHOOSECOLS(FILTER(A1:F1,D1="09h51m54.0s"),3))
Formula2: UNIQUE(CHOOSECOLS(FILTER(A2:F12,D2:D12="09h51m54.0s"),3))
Level: medium
Question: what is the lowest apparent magnitude when the object type is spiral galaxy, the constellation is leo minor and the ngc number is more than 3021?
Formula: MIN(FILTER(F1, (B1="spiral galaxy")*(C1="leo minor")*(A1>3021)))
Formula2: MIN(FILTER(F2:F12, (B2:B12="spiral galaxy")*(C2:C12="leo minor")*(A2:A12>3021)))
Level: easy
