Finder charts for use at the summit may be emailed as attachments to
ukirt-finders (at) jach.hawaii.edu
The “Subject:” field must include (anywhere) your project ID in square brackets, in the usual OMP format: [u/<semester>/<n>] – if not, the message will be deleted. This is not case sensitive; [U/07B/58] and [u/07b/58] are both valid ways to give the same project ID. Finder images should be attached to the email; the body can be left blank. Multiple files can be attached to a single email and will be handled separately.
File formats and size limit
Your charts will be accessed at the summit using a web browser and should not require translation or plugins to view. Acceptable file formats therefore include jpg, png, gif. Postscript is unacceptable, and we prefer that you do not use pdf files. Where necessary, please take a simple screen shot of images in another format and save as one of the preferred formats listed above. The system will silently delete any attachment which exceeds 100kbyte in size.
To avoid confusion at the summit, we ask that the following guidelines be adhered to:
- File naming: File names must be all one string (no spaces), with the first part of the string defining the target name and the final part of the string (after a mandatory underscore) defining the waveband of the image (either by name or by wavelength in decimal microns with “um” appended).
- Target names: must match exactly those used in your MSBs.
- Image information: You must include at least (i) North and East arrows (ii) a scale bar or other indication of scale of the image and (iii) an indication of where in the image your target lies.
Some examples of valid file names (note – no spaces, no non-alphanumerics apart from underscores):
And some Invalid file names:
FRS1350.png (no waveband information)
Elias 2 16_K.gif (spaces in the file name)
M104_2.2.jpg (no trailing “um” after the wavelength)
Here, with thanks to E Whelan, is an example of a finder chart which gets everything right (clear indication of scale, clear indication of the target, east and north indicated).
