Summary | 0002060: ASTAP, request to remove -fov parameter from the commandline | ||||
Description | Today after a routine check today, I had a weird problem with solving FITS images using CCDCIEL as front end and ASTAP. The problem only occurred with older FITS images produced by CCDCIEL. Using CCDCIEL they didn't solve but in loading in ASTAP they solved without problems. There was a difference in the values of SECPIX1/2. Some older FITS files from different origin had similar problems and was also caused by the fov parameter send. Normally there is no need for testing older FITS file. But nevertheless the problem can be fixed by removing the -fov parameter in the ASTAP command line. The -fov parameter is not required. ASTAP will extract the data from the FITS keywords. So I would suggest to remove this parameter allowing some flexibility. The current definition of -fov is image height since I use a square field for searching but that has changed in the past. Existing: C:\astap.fpc\astap.exe -fov 1.36 -z 1 -r 5 -f C:\Users\h\AppData\Local\ccdciel\tmp\ccdcieltmp.fits Proposed: C:\astap.fpc\astap.exe -z 1 -r 5 -f C:\Users\h\AppData\Local\ccdciel\tmp\ccdcieltmp.fits p.s. I also noted the definition of the two keyword below is now in line with MaximDL use: XPIXSZ = 6 / [um] Pixel Size X, binned YPIXSZ = 6 / [um] Pixel Size Y, binned | ||||

I remove the fov option: https://github.com/pchev/ccdciel/commit/a20641738429f246174f5bef8433d97675d7433c I was not sending the image height, but the max of height,width. This is probably the reason for the problem. Yes I fix XPIXSZ,YPIXSZ last autumn so it indicate the binned pixel size. This is now compatible with the SBIG extension definition but sure the old files are not compatible. |
