uploading a datafile with fainter-than observations

Hello Everyone,

I've done time-series photometry on two polars with very high amplitudes of variability over the course of their orbital periods. When at minimum, these objects are undetectable with my equipment, so I can only report fainter-than observations for parts of their light curves. Is it possible to submit fainter-than observations in a datafile? I've got several hundred of these fainter-than measurements interspersed in my light curves, so uploading them one-by-one would be a huge chore.

Best Regards,

Colin
