\r\n The General Observability Criteria in OWC has been designed to easily exclude events that are not going to be observable because \r\n they are too short for the given star magnitude to be reliably recorded. The user can also provide a hard limit on the minimum\r\n duration or the magnitude drop or a limit on the star magnitude for exclusion.
\r\n The filtering assumes that video recording will be used for the detection and is based on the aperture of the telescope to be used \r\n and the minimum desired number of positive detection video frames for the maximum predicted event duration.
\r\n The formula allows for a user provided magnitude adjustment factor so it can be tuned to particular personal conditions. \r\n Proving positive values for MagAdjust will adjust for having better conditions (e.g. darker skies or more sensitive equipment) while negative values\r\n will adjust for having worse conditions (e.g. light polluted skies or less sensitive equipment).
\r\n The formula does not use the star magnitude, the maximum predicted event duration or the magnitude drop directly however the user can configure \r\n preferred limits for these parameters and events that do not meet these limits will be excluded upfront without applying the formula. These extra \r\n parameters are included in the criteria as some observers prefer to set them directly as their hard limits of what they are comfortable \r\n to attempt to observe.
\r\n During the development and testing of the formula it was determined that the predicted magnitude drop does not have significant effect and is not\r\n part of the formula.
\r\n When enabled the formula will also adjust for magnitudes lost due to atmospheric extinction for lower altitude events.\r\n
