| System | alfosc |
| Command | expose |
| Arguments | [-d] [-t] [-f] [-n]<tt> |
| Type | DET |
| Short Description | Makes an exposure of <tt> seconds.
Remnant removal is made before the exposure starts, if the exposure time is larger then 60 seconds. If the option [-n] is used, no remnant removal is done.
If the option [-f] (fast mode) is used, the prompt will be returned when the exposure time is over and before the readout begins. If [-f] is used, make sure that "alfosc.wait-camera-state idle"-command is given before any "alfosc_camera_commands".
If the exposure time is larger than 300 seconds, the time left until the rotator reaches its limit will be checked. If there is not time enough to complete the exposure, an error will be generated and the exposure will not start. |
| Long Description | Makes an exposure of <tt> seconds.
Remnant removal is made before the exposure starts, if the exposure time is larger then 60 seconds. If the option [-n] is used, no remnant removal is done.
To abort the exposure press "Control-C". This command checks if ALFOSC, FASU and FAPOL are ready before beginning the exposure. If 90 seconds occurs and it is not ready this command will time out.
If the option [-f] (fast mode) is used, the prompt will be returned when the exposure time is over and before the readout begins. If [-f] is used, make sure that "alfosc.wait-camera-state idle"-command is given before any "alfosc_camera_commands".
If the exposure time is larger than 300 seconds, the time left until the rotator reaches its limit will be checked. If there is not time enough to complete the exposure, an error will be generated and the exposure will not start. |
