We are getting the following error messages upon running BPASS on a VLBA
data set and our unable to find the cause:
dubhe > BPASS1: TABSRT: OTBSRT ERROR 1
dubhe > BPASS1: FRQUOD: ERROR 1 SORTING CL TABLE
dubhe > BPASS1: DATSHF: ERROR 1 DETERMINING FULL SKY FREQ.
dubhe > BPASS1: BPCOPY: ERROR 1 SHIFTING SPECTRA
dubhe > BPASS1: Purports to die of UNNATURAL causes
