1. The 1st line gives column title.
2. Following lines give magnitudes and SNR. The 1st column is target followed by comma, from the 2nd to the 6th are magnitudes seprated by Space, and the last is the requested SNR. If one magnitude of a band does not exist, marking as '-1'.

Results:
('-1' represents that the exposure time can not be obtained.)
