PEPObs was developed from legacy code used to reduce photoelectric photometry submitted to the AAVSO PEP program. We have retained most of the original fields for backwards compatibility with old PEP reports. What follows is a guide to fields in the online form with formatting instructions. In the examples, the quotes ("") should not be included.
Note on Automatic Rejection of Low Signal-to-noise Data
The AAVSO has a policy in place that states positive observations having errors equal to or greater than 1.0 magnitudes are not accepted as is. For a given measurement, an error of 1.0 magnitude is equivalent to a signal-to-noise ratio of 1, meaning that the purported signal is indistinguishable from the average noise fluctuation in the data and statistically is not a significant detection.
