PNS MANUAL: Installing PNS DAS scripts

The PNS DAS scripts

A clear summery of PNS commands is here crib_sheet.pdf (30/11/08) and here crib_sheet2.pdf (19/03/10)

The PNS DAS scripts could be found in the directory /home/whtobs/pns. If this directory doesn't exist, the most updated version of the DAS scripts could be find as a tar file here. Unpack the tar file from the home directory of whtobs on the DAS control computer (taurus). The scripts should appear in the subdirectory /home/whtobs/pns/ .

In both the case, to install the commands, issue the following from the SYS> prompt on the "DAS central intelligence window": source pns/aliases .

The following commands are then available:
windowpnsEE set window parameters of PNSL and PNSR CCDs
windowpnsHa set window parameters of PNSHa CCD
smallwindow choose small 100x100 windows for quick-look
expose expose time "title" for science exposures
note this staggers the exposures to prevent simultaneous readout (and concomitant pattern noise)
exposeHaN(B) expose time "title" for science exposures
expose_allN(B) expose_all time "title" for science exposures (PNSL, PNSR and PNSHa)
note this staggers the exposures to prevent simultaneous readout (and concomitant pattern noise)
fluxstd fluxstd time "title" for flux standards
skys skys time for twilight sky exposures
skys_allN(B) skys_all time for twilight sky exposures
focuspns integrate on both ccds for 3000 s during tel focus run
arcs 80 second arc exposure; tells you to switch lamps on and off.
maskimageHaB mask images optimezed for the broad band filter
maskimageHaN mask images optimezed for the narrow band filter
flats internal flats exposure; tells you to switch lamps on/off.
finishpns end both arms' integrations and read out simultaneously.
abortpns ABORT both arms' integrations WITHOUT READING THE DATA.
readalias Re-read the macro definitions and aliases

In addition some standard macros are useful:
newtime newtime pnsl t or pnsr t; changes the exposure time of the respective channel
abort pnsl or pnsr; terminates exposure without saving data
