Good news is that the telescope is not willing to self destroy if incorrectly commanded. The low limit of pointing is at altitude of 10deg. | Good news is that the telescope is not willing to self destroy if incorrectly commanded. The low limit of pointing is at altitude of 10deg. | ||

We discussed the possibility of installing our stuff on Solaris - it seems this would be the cleanest solution, This Solaris has a C and C++ compiler, but it may be painful to get all the libraries we need to use to run there. The extreme example case being the PSQL database. The obtained images are physically on this computer. | We discussed the possibility of installing our stuff on Solaris - it seems this would be the cleanest solution, This Solaris has a C and C++ compiler, but it may be painful to get all the libraries we need to use to run there.

The operation of RTS2 may, at present, appear chaotic to the responsible CAHA staff, especially in case of GRB alerts. We believe that care should be taken to inform people around about the actions the telescope is performing in a simple and accessible way. | The operation of RTS2 may, at present, appear chaotic to the responsible CAHA staff, especially in case of GRB alerts.

The level of support of programs based on what has been found inside is, however, likely to be different than if we use them as they are. On the other hand, connecting rts2 to epics would bring a serious simplification. | ||
