Fasti is an innovative design for infrared detector control. ... to use largely accepted standards as boundaries, as a PCI bus, a parallel interface or a serial, and to use few of them . ... The building blocks of Fasti are: . ... the serial bus for controlling housekeeping devices (temperature and pressure sensors or motor controllers) and programming data acquisition . ... Though not so fast, and lacking some forms of data integrity check, this bus is so widely used to be nearly unavoidable. ...

NGC FRONT-END FOR CCDS AND AO APPLICATIONS Javier Reyes, Mark Downing, Leander Mehrgan, Manfred Meyer and Ralf Conzelman European Southern Observatory, Karl-Schwarzschild-Str. 2, 85748 Garching, Germany Abstract: The New General detector Controller (NGC) at ESO aims at covering optical, infrared and wavefront sensing applications with a single controller. ... In addition, the adaptation of the NGC frontend to the future ESO CCD head for AO and the control of the L3 devices is presented. ...

For historical reasons, it is useful to offer comparisons between the current WFPC2, and its predecessor WF/PC-1, which was returned to Earth in December 1993. Field format: WF/PC-1 contained 8 cameras and CCDs, each CCD having 800 x 800 pixels. ... Many differences derive from the fact that the WF/PC-1 CCDs were thinned, backside illuminated devices whereas the WFPC2 CCDs are thick, frontside illuminated devices. ... WFPC2 devices have much less CTE error, and hence no preflash is used. ...

... The mirrorCtrl mirror controller actor controls one telescope mirror. It accepts desired orientation and commands mirror motion accordingly. ... It is presently designed to command a Galil mirror controller , but one may add support for other low-level motion controllers. mirrorCtrl is written pure Python. ... Home the desired actuators, where actuator list is a comma-separated list of actuator letters A through F (but some mirrors have fewer than 6 actuators). 2.5m M1 valid actuators: A-F . ...
