This is the first version of ETC. With the clarification of the technical characteristics of the Spektr-UF instruments during the preparation for the launch and its operation in orbit, the developed ETC will be updated.
Planned Features for Future Versions:
- Add the ability to normalize the astronomical objects spectrum not only by its apparent magnitude but also by the magnitude in other filters;
- Add various absorption curves in the Galaxy for the user's choice apart from (Cardelli et al., 1989);
- Combine calculations of the Spektr-UF ETC with the calculations of the zodiacal light contribution and geocoronal emission for a specific object and time of observation;
- Add the ability to divide the total observing time to solve a specific problem into sub-exposures. And also to display warnings to the user related to technical limitations that may arise during observations (for example, a warning about possible overexposure of the detector).
