Description
mextract seems to return a one entry vector instead of a null vector when no
matches are found. The vector's entry is the first entry of a previous
vector of the same name. See commands below,
dvo: catdir /data/ipp022.0/ndeacon/hispeedzy-feb11
dvo: skyregion 190 191 -2 -1
dvo: avextract ra dec
dvo: echo ra[0]
190.028796778
dvo: echo ra[]
108
dvo: skyregion 190 191 -62 -61
dvo: mextract ra dec where (y>0.0)
dvo: echo ra[0]
190.028796778
